Buddha has talked about two kinds of nirvana. One he calls nirvana with substratum. The tree has disappeared, the tree of desires. The foliage, the leaves, the flowers, the fruits – everything has disappeared. But the roots are still there underground, hidden in the dark soil. From the outside the tree has been removed, but the tree is still capable of renewing itself again. The substratum is still there, the seed has not been burnt yet. This he calls nirvana with substratum.
This is exactly the same that Patanjali calls sabeej samadhi – samadhi with seed. It is very difficult from the outside. The tree has been completely removed, but underneath the soil the roots are still alive waiting for the right moment to sprout again. Rains will come and they will sprout. They are waiting for their season, for the moment again to assert.
This is the state when many times you have come to the point where mind disappears, no-mind is felt, but again mind comes back, again it sprouts. You reach to a peak. In that moment of that peak experience you think all is finished, now you will never be falling back to the valley of darkness. You think that you will never go back into those ugly and miserable days, that the dark night of the soul is over, that the morning has arrived, that the sun has arisen.
But again one day you suddenly find you are slipping back into the darkness – again the valley, again light is no more, again that peak experience is just a memory. And one starts becoming doubtful whether it has happened or not, or “Have I been just imagining? Or maybe I was just dreaming.”…Because if it had happened, then where has it gone? Where is that sunlit peak? Where are those moments of ecstasy? And misery is back and anguish is back and agony is back – you have fallen into hell again. This happens many times.
This Buddha calls nirvana with substratum; sabeej samadhi in Patanjali’s words. Manifestation of the world is gone but the unmanifested seed remains.
The second nirvana Buddha calls the nirvana without substratum. In Patanjali’s words nirbeej samadhi – seedless samadhi. Not only the tree has been destroyed, but the seed also burned. A burned seed cannot sprout again; all substratum is gone. Then you remain on the peak forever, then there is no falling back.
That’s what Buddha says in yesterday’s sutra: Someone who has set out in the vehicle of a bodhisattva should decide that “I must lead all the beings into nirvana,…into that realm of nirvana which leaves nothing behind.” Which leaves no substratum, no roots, no seeds behind.
The third question:
What is the Zen approach towards sex? The Zen people seem to have a neuter gender, or asexual aura about them.
