Realization itself is within the inner consciousness. It is an inner experience that has no connection with the lower mind-system and its discriminations of words, ideas and philosophical speculations. It shines out with its own clear light to reveal the error and foolishness of mind-constructed teachings, to render impotent evil influences from without, and to guide one unerringly to the realm of the good non-outflowings.

(The Lankavatara Sutra)
