The mind itself is a potent instrument for change, the only one there is.
All change must take place in the mind first,
for all action is a result of thought and the resultant impulse or motivation.
The ego attempts to fill awareness with a constant stream of thoughts, impulses, images, and feelings, all of which have one purpose:
To absorb your attention completely and use the energy of awareness to maintain perception, understanding, and experience, within the narrow limits it has established.
Only thus can the fiction of its existence be maintained.
