My mind is a chest of drawers. When I wish to deal with a subject, I shut all the drawers but the one in which the subject is to be found. When I am wearied, I shut all the drawers and go to sleep.
When you completely extract yourself from anything familiar, you start reverting back to that state of mind where you're having conversations with yourself, and that's where the weirdest and most honest ideas come from.
As long as the mind is seeking to fill itself, it will always be empty. When the mind is no longer concerned with filling its own emptiness, then only does that emptiness cease to be.
Only when the mind is still, tranquil, not expecting or grasping or resisting a single thing, is it possible to see what is true. It is the truth that liberates, not your effort to be free.
