Osho : Kundalini and the chakras are not located in the physical body. They belong to the etheric body, but they have corresponding points within the physical body. It is like when you feel love and you put your hand on your heart. Nothing like ”love” is there, but your heart, your physical heart, is a corresponding point.
When you put your hand on your heart, you are putting your hand at the chakra that belongs to the etheric body, and this point is approximately parallel to your physical heart. Kundalini is part of the etheric body, so whatever you achieve as progress on the path of kundalini does not die with your physical body; it goes with you.
Whatever is achieved will remain with you because it is not a part of your physical body. If it were a part of your physical body, then with each death it would be lost and you would have to begin from the very beginning. But if someone reaches the third chakra, this progress will remain with him in his next life. It will go with him; it is stored in the etheric body.
When I say that the life energy goes through kundalini, I mean kundalini as a passage – the whole passage connecting the seven chakras. These chakras are not in the physical body, so everything that can be said about kundalini is being said about the etheric body. When the life force passes through kundalini, the chakras will begin to vibrate and flower.
The moment energy comes to them, they become alive. It is just like when hydro-electricity is created; the force and pressure of the water rotate the dynamo. If there were no pressure and no water, the dynamo would stop; it would not work. The dynamo rotates because of the pressure. In the same way, the chakras are there, but they are dead until the moment the life force penetrates them; only then do they begin to rotate.
That is why they are called chakras. ”Chakra” is not exactly translated by the word center, because center means something static and chakra means something moving. So the right translation would be wheel, not center; or, a dynamic center, or a rotating center, a moving center. Chakras are centers until the life force comes to them.
The moment the life force comes to them, they begin to be chakras. Now they are not centers, they are wheels, rotating. And each wheel, by rotating, creates a new sort of energy. This energy is used again to rotate further chakras. So as the life force passes through each chakra, it becomes more vital, more alive.
Kundalini is the passage through which the life force moves. The life force is located in the sex center, stored in the sex center, the muladhar. It can be used as sex energy; then it generates a particular life, a biological life. Then too it creates movements, then too it creates more energy; but this is biological. If this same energy moves upward, the passage of kundalini is opened. The sex center, the muladhar, is the first to open.
It can open either toward biological generation or it can open toward spiritual generation. The muladhar has two openings, a lower one and an upper one. In the passage of kundalini, the highest center is the sahasrar, of which the brahma randhra is the middle point. The opening of the brahma randhra is one way toward self realization.
Other ways are also possible in which the passage of kundalini is not used, but they are more arduous. In these other methods there is no question of kundalini, then there is no movement through this passage. There are Hindu methods: raja yoga, mantra yoga, and all the many techniques of tantra.
There are Christian methods, Buddhist methods, zen methods, taoist methods. They are not concerned with kundalini awakening; that passage is not used. They use other passages, passages that do not even belong to the etheric body. Astral passages can be used. The astral body, the third body, has its own passage. The mental body, the fourth body, has its own passage. All of the seven bodies have their own passages.
There are many yogas that have nothing to do with kundalini. Only hatha yoga uses kundalini as a passage. But it is the most scientific and the least difficult. It is an easier step-by-step method for gradual awakening than the other yogas. Even if the kundalini passage is not used, there are sometimes sudden awakenings of the kundalini.
Sometimes things happen that are beyond your capacity, sometimes things happen that you cannot conceive; then you are completely shattered. Other passages have their own preparations. Tantric or occult methods are not kundalini yoga. Kundalini yoga is only one of so many methods, but it is better to be concerned with just one.
