One sits alone in isolation, one absorbs oneself within, one impresses in the mind the well-considered teachings, and one goes on impressing this within the mind continuously, the very mind that is doing the impressing.
— Buddha Shakymuni, The Elucidation of Intention Sutra
--translated by Robert Thurman, Essential Tibetan Buddhism
