To concentrate implies bringing all your energy to focus on a certain point; but thought wanders away... Whereas attention has no control, no concentration. It is complete attention, which means giving all your energy, the energy of the brain, your heart, everything, to attending.
To revolt within society in order to make it a little better, to bring about certain reforms, is like the revolt of prisoners to improve their life within the prison walls; and such revolt is no revolt at all, it is just mutiny. Do you see the difference? Revolt within society is like the mutiny of prisoners who want better food, better treatment within the prison; but revolt born of understanding is an individual breaking away from society, and that is creative revolution.
If you have this extraordinary thing going in your life, then it is everything; then you become the teacher, the disciple, the neighbour, the beauty of the cloud - you are all that, and that is love.
A mind that is disciplined, controlled, is free within its own pattern; but that is not freedom. The end of discipline is conformity; its path leads to the known, and the known is never the free.
Discipline does not mean suppression and control, nor is it adjustment to a pattern or ideology. It means a mind that sees 'what is' and learns from 'what was'.
To understand the totality of this extraordinary thing called life, one must obviously not be too definite about these things. One cannot be definite with something which is so immense, which is not measurable by words. We cannot understand the immeasurable so long as we approach it through time.
It is man's pretence that because he has choice he is free. Freedom is pure observation without direction, without fear of punishment and reward. Freedom is without motive; freedom is not at the end of the evolution of man but lies in the first step of his existence.
