"The Only Revolution" was published in England 10 years after the release of the third book of "Problems of Life", as if continuing and completing this trilogy. This luminous work is thoroughly permeated with thoughts about meditation. “Meditation comes only when your heart is truly open, not open with the key of thought, not immune from danger with the help of the intellect, but open in the same way as the cloudless sky is open: and then meditation comes without your knowledge, without our call... Meditation occurs without the participation of the mind, which always calls for it: meditation appears from the peace of consciousness, not inside, but outside it, not on the periphery of thought, but where thought has no access. Therefore, we have it. and we do not remember: memory is always from the past, and meditation is not a resurrection of the past. Meditation comes from the fullness of the heart, and not from intellectual brilliance and abilities."
