Yoga has been used to kill the mind; breathing can be used to kill the mind. There are rhythms of breath, subtle vibrations of breath, which can be very, very drastic to the delicate mind. The mind can be destroyed through them. These are old tricks. Now the latest tricks are supplied by science: LSD, marijuana, and others. More and more sophisticated drugs will be available sooner or later.
I am not in favour of stopping the mind. I am in favour of watching it. It stops of its own accord — and then it is beautiful When something happens without any violence it has a beauty of its own, it has a natural growth. You can force a flower and open it by force; you can pull the petals of a bud and open it by force — but you have destroyed the beauty of the flower. Now it is almost dead. It cannot stand your violence. The petals will be hanging loose, limp, dying. When the bud opens by its own energy, when it opens of its own accord, then those petals are alive.
