Yogis say that the prana has ﬁve different shapes, workings, energy ﬁelds in you. You will say simply ”breathing” is enough. We know only two things – exhalation, inhalation – that’s all. But yogis live in the world of prana and they have come to know subtle differences, so they have made ﬁve divisions. Those divisions have to be understood. They are very signiﬁcant.
First is prana, second is apana, third is samana, fourth is udana, ﬁfth is vyana. These are ﬁve prana manifestations in you, and each has a different work to do inside.
Prana, the ﬁrst, is respiration.
Apana, the second, is a help to excretion; it helps to cleanse the body of all excreta. The bowel movement comes from apana, and if you know how to work on it, you can cleanse your bowels as nobody else can. Yogis have the cleanest bowels. And that is very, very meaningful because once the bowel is totally clean, once your intestines are perfectly clean, your whole being feels light, as if you can ﬂy. The burden disappears.
Ordinarily your intestines carry much rotten excreta – your whole life’s, layers upon layers. Inside, the inner walls of the intestine, excreta goes on accumulating dry and hard. It creates many poisons; it makes you heavy. It makes you more available to gravitation. Much emphasis is given in yoga to cleanse the whole stomach so that no toxins remain in it because otherwise they go on circulating in your blood, they go on circulating in your brain, and they create a particular energy ﬁeld around you which is heavy, dark, black.
When the intestines are perfectly clean and clear, the aura arises around your head; and people who have perceptive eyes can see it very easily. And you feel as if you are like a feather.
The third, samana, is digestion and providing body heat. If you know the function of the third and if you become aware where it is, your digestion will become absolutely perfect. Ordinarily you eat much but you don’t digest it. You go on eating and you never feel satisﬁed. You go on stufﬁng the body without digesting it. If one knows how to use samana, a small quantity of food will give him more energy than a big quantity of food ever gives to you. That’s why yogis can fast for many days without any harm to their body. Once in a while they will take a little quantity of food, and they will digest it totally. Your food is not totally digested. That’s why your excreta can become food for some other animal and he can digest it. Much food value is still left in it.
And the third provides the body heat also. In Tibet they have developed the whole system of body heat, creating body heat, on samana. They breathe in a certain way, in a certain rhythm, so that the samana vibe functions efficiently within their body. They create much heat. They can create so much heat that snow is falling and a Tibetan lama will stand naked – perspiring – under the open sky. All over is snow; and you will be freezing. You will not be able to come out of the house, and he is standing in the falling snow – perspiring.
Fourth is udana, speech and communication. When you speak, the fourth type of prana is used. And the same type of prana can be trained; if that prana can be trained you become a hypnotic speaker, or you can become a hypnotic singer. Your voice can have a hypnotic quality. Just listening to it, and people can be magnetized.
And the same is used for communication. People who are in a difﬁculty of how to communicate – and many people, millions of people, are in that difficulty how to communicate, how to relate to others, how to love, how to be friendly, how to be open, how not to be closed – they all have some difficulty of udana. They don’t know how to use the prana energy which makes you ﬂowing and makes your energy become open and you can easily reach the other and there is no block.
And fifth is vyana, coordination and integration. The ﬁfth keeps you integrated. When the ﬁfth leaves the body, you die. Then the body starts disintegrating, deteriorating. If the ﬁfth is there, even if your whole breathing stops, you will remain alive. That’s what yogis are doing. When yogis exhibit that they can stop their heart, they stop four – the ﬁrst four pranas – they keep on the ﬁfth. But the ﬁfth is so subtle that there exists no instrument yet which can detect it. So for ten minutes you can observe in every possible way and you will see that the yogi is completely dead and your doctors will certify that he is dead, and he will come back. The ﬁfth is the most subtle, the very thread which keeps you as an organic unity.
If you can know the ﬁfth, you will be able to know God, not before that. Because the function of the ﬁfth within you is the same as God’s function in the totality. God is vyana; he is keeping the whole together – the stars, millions of stars, the inﬁnity of space, all together. And your whole body is a miniature. It has everything that the whole has, nothing is lacking. If you can understand your totality, you will have understood the totality of all.
