I do not say think in the heart, I say concentrate, concentrate the energy, concentrate the consciousness, concentrate the aspiration, concentrate the will. Concentrate. One can have an extremely intense concentration without a single thought, and in fact it is usually much more intense when one does not think. (Silence) It is one of the most indispensable things to do if one wants to succeed in having self-control and even a limited self-knowledge: to be able to localise one's consciousness and move it about in the different parts of one's being, in such a way as to distinguish between one's consciousness and one's thought, feelings, impulses, become aware of what the consciousness is in itself…
This consciousness must be mobile, and one must know how to distinguish it from the other parts of the being which in fact are its instruments, its modes of expression. The consciousness must make use of these things, and not you, mistake these things for the consciousness.
