''In the Dead of Night..''- Ajahn Chah

In the beginning you must rely on a teacher to instruct and advise you. When you understand, then practice. When the teacher has instructed you follow the instructions. If you understand the practice it's no longer necessary for the teacher to teach you, just do the work yourselves. Whenever heedlessness or unwholesome qualities arise know for yourself, teach yourself. Do the practice yourself. The mind is the one who knows, the witness. The mind knows for itself if you are still very deluded or only a little deluded. Wherever you are still faulty try to practice right at that point, apply yourself to it.

Practice is like that. It's almost like being crazy, or you could even say you are crazy. When you really practice you are crazy, you ''flip.'' You have distorted perception and then you adjust your perception. If you don't adjust it, it's going to be just as troublesome and just as wretched as before.
