Man has seven centers. The lowest is the sex center and the highest is the samadhi center, and between these two there are five more centers. It is a ladder. When all the seven centers of a man are in tune and harmony with all the seven centers of a woman, then you have found the soul mate. It has happened only once in a while: with Krishna and Radha, with Shiva and Shakti. It could have also happened to Majnu and Laila if they had been allowed to meet, to Shiri and Farhad if they had been allowed to meet but society hindered them.

And remember, Krishna and Radha were not allowed by society either; it was not a legal marriage, it was illegal. Radha was not Krishna’s wife but just a girlfriend. And with Shiva and Shakti, the parents were very much against Shakti getting married to Shiva. He looked a very strange man – he was! It was against parental advice that Shakti jumped into a love affair with Shiva.

But only once in a while has this happened, and this seems to be natural. Whenever it happens, absolute oneness is felt – unity, not union. Two persons utterly disappear into each other; there is not even a small, thin screen dividing them, there is no division at all. It is unio mystica. Two persons function as if they are one person: two bodies, but one soul. It is absolute harmony. It is love at its peak. No meditation is needed; this love is enough.

You must have seen Shiva temples in India; you must have seen the shivalinga. The Shivalinga simply represents the orgasmic state of these two lovers. Shivalinga simply represents Shiva as masculine energy; and just below shivalinga – the phallic symbol – is the symbol of Shakti: yoni. Shivalinga and Shakti’s yoni are meeting; they have become one, they have disappeared into each other. They have lost all personality. That’s why it is the only image in the world which has no face.

Just pure energy is symbolized by lingam and yoni, by the male sexual organ and the female sexual organ. Energy is simply represented – creative energy, vital energy, energy out of which the whole of life flows. Neither does Shakti have any face nor does Shiva have any face; those faces are no longer meaningful, the personalities have disappeared. It is a meeting of pure energy; and only pure energies can dissolve into each other because if you have a solid personality it will obstruct dissolution. Only pure energies, liquid, can enter into each other and become one. If you put two rocks together they may be together, but they cannot become one. But if you pour water into water, it becomes one.

At this highest peak where all the seven centers meet, persons disappear, only energies remain, a play of energy, a play of consciousness. And the joy is constant; it is orgasmic. It is a spiritual communion. No meditation is needed for such a couple because for such a couple love is meditation enough. It is a mystic phenomenon; it is transcendental. But it is very rare. Amongst millions and millions of people, it will happen once. It will be almost a chance meeting.

Below it, there is another meeting: six centers meeting. That too is rare. If the first is one percent, the second is only two percent. It is union, not unity. It is not a cosmic, mystical union, but still something very close to it: an aesthetic union, an artistic phenomenon, a poetic experience.

The first can be understood only by those who have known samadhi, satori. The second can be understood by poets, painters, dancers, musicians.
