THE THREEFOLD SKY PRACTICE
"The practice is called mingling the three skies, the three spaces, or the threefold sky. What are the three skies? Externally, the outer sky is the empty space, the openness right in front of you. Inner sky is the empty quality of mind, and the secret sky is the empty awareness.
There are three words, but actually it is one meaning, so the last word, mingle, means they are all combined into one. The external sky is called space because it is unimpeded, unblocked. It is not like a wall or something. It is empty and it is open. The inner sky is the empty mind, which all sentient beings have. Otherwise, mind would be like a piece of wood or a stone. Since mind is sentient, that is the mind referenced in the inner sky’s empty mind. The secret sky is the empty awareness, which is the essence of mind. Once you recognize the essence, the three skies are unified. Otherwise, without recognizing the essence of mind, you will only have unified two skies, not three.
Awareness is understood to be and defined as the essence of the mind. To understand what is meant by rigpa or the essence of mind, we can use the example of our own body. The heart in the main trunk of the body is like rigpa, and the arms or legs are like mind. From one perspective, it is one thing, but from another, there are two. To see rigpa, you have to look to the main trunk of the body. If you are distracted and in mind, it is like looking outwardly, away from the body. You are following yourself somewhere else, and you have no way to meet the essence. If you look into the origin, the source of where mind is, it is.like looking at where the arm attaches to the trunk. You come back to the mind essence, the heart is in the trunk of the body. That is why it says that sentient beings look away, and the Buddha looks toward (the mind’s essence). Awareness or rigpa is the trunk of the body; dualistic mind is like an appendage. If you look further out the arm to the hand, will you see your own heart? No. That is the difference between looking away and toward. If I want to see my heart and look further and further away, will I see it?
We do not see through dualistic mind. If you look toward the mind’s essence, you will get to the heart of it. That is the example. If you practice mingling the threefold sky, you need to recognize awareness; otherwise, it becomes an instruction in mingling the two skies. Mingling the two is something all sentient beings do. They hold their space outside, and inside they have mind. But in the moment of recognizing awareness, the three skies are automatically mingled, because at that moment there is no fixation on outer objects. There is no holding onto the mind, which perceives. There is no dualistic experience. You can easily teach about the mingled three skies, but it will probably only become the practice to mingle the two skies.
Again, in the mingling of the three skies, the outer sky is the empty space, the inner sky is the empty mind, and the secret sky is the empty rigpa, or awareness. In the secret space of rigpa, grasping and fixating are both gone. The three skies are automatically mingled when you have recognized rigpa. If you have not recognized rigpa, you are trying to construct the mingled three spaces. As long as you try to construct something, it is not rangjung, which means self-existent rigpa or self-existing awareness. The basis of the mingled three skies is rangjung yeshe, self-existing wakefulness. It is self-existing because it doesn’t have to be constructed and wakeful because it has cognizance. Without recognizing rigpa, it becomes nonarisen, unknowing.
In the moment of recognizing rigpa, you don’t have to mingle the three spaces; they are self-mingled automatically. Otherwise, we usually have the concept that the space is there, and that we are here watching; we have this dualistic setup. But in the moment of rigpa, this fixation falls apart. The difference between sems, dualistic mind, and rigpa is that sems has fixation and rigpa does not.
In short, it is like this: you don’t need to take charge of space outside. You don’t need to take charge of the space within. Just totally disown all three—outer and inner spaces and the secret space of rigpa—as they are already mingled. They do not need to be mingled.
Your eyes need to connect with space and not look down at the ground. Direct your eyes toward space. For sure, the mind is empty. Leave this empty mind within rigpa. This is called already having mingled the three spaces. It is then possible to be free from fixation. Any attempt to mingle the three spaces is always fixation. If you think of the space outside and the space within and then think, “I should mingle these two and then add rigpa,” we should not call this `mingling the threefold space’, but instead `mingling the threefold concepts.’ If we call `three concepts’ the state of rigpa, it makes concepts more important than rigpa.
Why should we engage in this practice? Because space is perfectly pure, empty, and totally unconfined. There is no center, no fringe, and no edge in any direction whatsoever. Directing the gaze into the middle of empty space is an aid for allowing rigpa to be similarly unconfined and all-pervasive.
Outer space transcends arising, dwelling, and ceasing. This is the example. The ultimate meaning is that rigpa is all-pervasive and empty, with no end, like space. In the context of means and knowledge, this practice is the means, method. Simply leave rigpa in unconfined external space; there is nothing to arrange. Within this state, there is a shimmering configuration of light and something moving about. Direct your gaze toward this configuration. This is beneficial.
What it comes down to is this: If you have recognized rigpa, it becomes, automatically, the general mingling of the three spaces, the three skies. But if you have to try to mix it together, then it becomes quite difficult. You think, “First, there is the sky, then there is my mind, and finally there is rigpa.” It becomes very hard because it is interrupted by concepts.
The starting point is to recognize mind essence. When we talk about recognizing mind, we talk about the pointing-out to the essence of mind, not to mind. Nobody asks the lama to please point out the mind. We say, point out the mind essence; we don’t say point out the mind. That is the difference, and we should understand its meaning. We don’t have to point out mind, as everybody already has mind. If one is sentient, a sentient being, one automatically has dualistic mind. The student requests to a precious master, “Please show me mind essence.” The essence of mind is rigpa, awareness. And what is rigpa? It is self-existent wakefulness, whereas the mind is nonexistent stupor.
In order to practice like this, you first have to recognize the mind essence. Then it is possible to practice mingling the threefold space. Without that, I can tell you words, saying that the eternal sky is empty space, which is free from anything that can obstruct or impede, such as mist, dust, or clouds. That is the example for the external empty sky. Sky is unsupported; there is no focal point in the empty sky. Baseless space doesn’t have any reference point that we can focus on. If there is a reference point it is shamatha. Unsupported space completely destroys our sense of shamatha, fixating concentration. That is why it is very beneficial. Best is the sky; second best is an endless ocean. You can go to the ocean bank, shore, and look out; that is the second best.
Space is basically complete openness, unobstructedness. It doesn’t mean the blue thing we can see up there. This blueness we see is called the ornament of the sky. It is said according to the scriptures that because of the reflection of the sunlight on the southern slope of Mount Meru, which is made of sapphire, our sky and ocean are blue in appearance. However, if you are higher up, further up, the sky doesn’t have any colors; it is black. But if you fly further and further, straight up, you will never find a place where you touch something. There is no end to it. No matter how many billion—or countless—aeons you fly, there is no end. Likewise, if you fly down through the earth to what is called the Golden Base, you will also go endlessly through, without finding any bottom anywhere. If there is no above and no below, then how can there be south, east, west, and north?
To practice this, you should take into experience what is really meant by space— that there is no top, no bottom, and no limit to south, east, west, or north. Space is complete without any limitation in any direction. That is what you focus on to begin with for the three skies. That was about the external sky. Now let’s turn to the inner sky of the empty mind. Does mind have a place that it comes from, dwells, or goes to at any point? We find that it does not. The external sky is empty and so is the inner sky, the empty mind; it’s empty as well. If something has a place where it arises, a place where it stays, and a place where it ceases, it wouldn't be empty. Since the mind is without any arising, dwelling, or ceasing, it must be empty. That was the second sky.
Now for the secret sky of empty awareness, we should first understand what mind essence is and how it is uncompounded. Dualistic mind has thoughts, thinking. Namtok, (rnam rtog), dualistic thought, is nram pa, an appearance, manifestation of the five sense objects, and rtog pa, which means to conceptualize, hold onto that. That is thinking. But the secret space of rigpa is without any thoughts. While being free from thoughts, its essence is empty; its nature is cognizant, or luminous; and its capacity is unobstructed.
Dualistic mind is decorated with thoughts, dualistic thinking. Thoughts are not something that stay by themselves. Thoughts arise, disappear, arise, and disappear, one after the other. That is what causes all the confusion. We sentient beings run after each thought that arises, which is why we forget the essence. In the secret space of empty rigpa, even though it’s devoid of any conceptual thinking, there is still a wakefulness. Dualistic mind is decorated with the conceptual thoughts, and rigpa is decorated or adorned with basic wakefulness.
Sems falls under the power of the three times but rigpa does not. Sems is always involved in thoughts about past, present, and future. Rigpa is devoid of these thoughts.
The difference between sems and rigpa is this: while sems is empty and cognizant, it has no awareness of its own essence. It has not taken hold of this empty cognizance. It is like the example of not identifying where the heart is and instead looking away from the body to find it. Having not recognized this empty cognizance, the mind of sentient beings is called the unity of being empty and cognizant with a core of nonawareness or ignorance. On the other hand, the mind of a yogi and a practitioner is the unity of the empty and the cognizant with a core of awareness. The difference lies in knowing how to look, as in the example of looking toward one’s own heart or looking out and away—out the length of the arm to find the heart. If you recognize where the heart is, you meet the heart or the essence of mind, rigpa, which is the essence, nature, and capacity. If, instead, you look away from the heart, the essence evolves into the three or five poisons, and you wander in samsara.
Since you are quite intelligent, you can understand this one point, which is what it all comes down to: recognize your own heart as in this example. Recognizing our mind essence is the main point of every teaching—whether it is samsara, nirvana, or the path. If you look and say, “I am trying to find my heart,” but you look down the arm to the hand and further away, you will never find your heart.
Finally, the smart person will look the right way and say, “Oh, here it is.” That is the example. Just like the most important part of the body is the heart, likewise, the most important point of the dharma, samsara, nirvana, and the path, is mind essence. You find the essence, the heart, by looking the right way, connecting with it. In so doing, you see nothing; there is nothing to see. Still, everything is vividly seen. It is said that this essence is endowed with the threefold wakefulness of essence, nature, and capacity. Actually, seeing this is not the thing seen—it is seeing that there is nothing seen.
In the Kagyü teachings it says, “Nothing whatsoever, yet everything arises from it.” ‘Nothing whatsoever’ refers to the empty essence, which everything arises from—it is the cognizant nature. That is the same as in the Nyingma terminology: the empty essence, yeshe; the cognizant nature, yeshe; and so on.
The essence is empty, cognizant, and unobstructed. This is what one has to touch base with. It is said that in the beginning one should touch what should be touched or connected to. Here there is nothing to connect to. There is not a thing that one gets and reaches, because the essence is without anything to hold or to touch. If you want something to hold, then there are plenty of thoughts to hold on to. Not touching something is called nonaction, which means free from concepts. It is said that one nonaction outshines all activities, because this moment of nonaction destroys the three poisons.
There is actually no other agent than this that can clear away the three poisons. The three poisons always follow after a conceptual thought. If there were no conceptual thoughts to begin with, there would be no three poisons to follow after that. Therefore, it is said that one nonaction outshines all activities or doings. The three poisons are not something that we can kind of prohibit or try to bury, burn, wash away, or flush away. Not even the smartest person in this world can handle the three poisons. If you try to suppress mind poisons, they just come back up again; it is impossible. Of course, you can try to be patient, but that won’t uproot the three poisons.
It is only the empty essence and wakefulness that can totally annihilate the three poisons. What is meant by yeshe? The basic word is shepa (shes pa), which means knowing or being awake. There is no sense of being oblivious or not knowing. While it is free from action and concepts, it still knows whatever there is to know. That is how the essence is. You are mistaken if you think, “Oh the essence is nothing whatsoever. It is merely a blank state, like being hit and knocked out with a stick.” It is not like that at all. It is unobstructed, being completely empty. It is empty while cognizing, cognizing while being empty. We don’t have to manufacture that; it is automatic. People can’t make the essence anyway.
It is beyond being cleared and obscured, just like the flame of a butter lamp. It is uninterrupted like the flow of a river. But then the bandits of conceptual thoughts have taken it and tied it up with the sense objects and consciousness. In the past, we wandered endlessly in samsara, and if we don’t recognize that, samsara will continue endlessly. There is nothing more essential or important than this. Putting this into practice is like the wish-fulfilling jewel, because when we die, we don’t have any free will whatsoever. If we have grown accustomed to rigpa, it means we are free from the fixation of the three poisons, which are the basis for continuing in samsara. Once we attain stability in the essence, being in the three realms of samsara is like playing around.
To reiterate, the threefold sky practice is as follows: Outwardly, there is empty space, which means there is nothing to focus on; there is no focus, nothing to rest the attention on. That is the external space, the outer sky. The inner sky is the empty mind, the emptiness of the mind within. The secret space is the empty rigpa that has been recognized, the knowing of empty mind. These three become mingled into one. If you practice this very well, then when you die you will mingle with primordial purity. The threefold sky practice is the ultimate phowa, for a Dzogchen practitioner.
You sit with the eyes directed toward midair, without focusing on anything and without thinking of space inwardly. It is said, “In unsupported space, place nonfixated rigpa.” Do not think about space; leave the inner mind without fixation. Do not form any thought such as, “I am looking into the sky,” or anything like that.
The secret space of rigpa is the knowing of this emptiness. Do not direct the mind outwardly but recognize mind essence. That is called the secret sky of rigpa. In this way, you naturally let outer, inner, and secret be undivided. That is called mingling. Without thinking of sky outwardly, and without forming any thought inwardly, you automatically mingle the threefold sky.
The first key point is to recognize the mind essence, rigpa. Once you have done that, repeat that recognition in short moments many times; that is the real way to mingle the three skies. When you are sitting outside, aim into space. It means that your eyes can look toward the open sky. Your eyes can face toward the outer empty sky, but really, your mind faces toward the empty rigpa. If you do not recognize rigpa, then you take outer space as the object and dualistic mind as the subject. Then you create this dualistic setup, but after recognizing rigpa, you have no duality like this.
Sit outside letting the eyes face toward the open sky and the inner mind face toward rigpa. That doesn’t mean you have to sit and hold this unity of the three skies. Just look once and then completely relax, let go. Automatically the three skies are mingled. The perfect mingling occurs by itself, automatically. In other words, space or sky means no point of reference. There is no thing to look at, right? In space, is there anything to focus on? Focus on no focus. In unfocused space, abandon awareness unsupported.
QUESTION: When we practice mingling the threefold space, firstly, do we concentrate on space far away for a long time?
RINPOCHE: First look away, then lead toward you; then it becomes all-pervasive. But actually, it is the same. Without fixating outwardly, immediately to do that is okay. You can stay that way outwardly and slowly look towards. Wherever the eyes are placed is space—far away, close, and everything inbetween is the same space.
If you leave it out in space, then it turns into a conceptual object. Once brought towards, out and in are the same, no division. There is really no difference; it is just a matter of close or far. This is a method; if you do not do it, it is perfectly all right. Away is empty space; close is empty space. The only reason to pull the space towards is to avoid sitting and watching space as being over there as a focus. There is nothing to think about. Simply rest in the all-pervasiveness. Don’t dwell on the appearance; rest in rigpa itself."

~ from Vajra Heart Revisited: Teachings on the Path of Trekcho
"Kyabje Tulku Urgyen Rinpoche’s impeccable qualities were evident to all who met him and received pith instructions and empowerments from him. His teachings on mind nature and the path of the Great Perfection were unparalleled. He had confidence and utterly pure trust based on the personal, direct understanding that buddha nature really is present in every sentient being. Just like oil is present in each and every sesame seed, any sentient being can realize the awakened state and thus has the basis for enlightenment.
These pith instructions in Vajra Heart Revisited are concise, brilliant expositions on the path of Trekcho, starting with the ground, the preliminaries, shamatha, and viphashyana, Three Vital Words, up to and including teachings on guru yoga, and bardo. They are extremely clear explanations on all aspect of practice that the Dzogchen yogi can use as a manual of guidance and inspiration. They include key topics such as differentiating mind and awareness and threefold sky practice, among others. It is all that is necessary to attain full mastery and realization.
The depth of Kyabje Tulku Urgyen Rinpoche’s actual understanding was unsurpassed, and many Nyingma and Kagyü masters stood in awe of his comprehensive knowledge. He had thoroughly studied and practiced the Atiyoga, and his teachings on Dzogchen transformed the lives of those he touched with gentle, penetrating clarity. As a meditation teacher and a master of initiations, he was without peer.
As he said, “We should focus our minds on simplicity, the state of buddhahood, nonconceptual wakefulness… Although you will not arrive at enlightenment immediately, if you aim towards it, as if intending to go to Bodhgaya, then no matter what happens on the way, if you never give up you will arrive. Since harm occurs in the mind, whatever disturbances arise in this body from aggregates, elements, and sense factors, just let go again and again into unfabricated naturalness. Then you will reach your destination, the state of Buddhahood”.
