We humans are actually not that far from enlightenment. Our five senses are like the Emanation Body of a Buddha; our dream body, which is similar to the after-death form, is like a Buddha’s Beatific Form; and the basis of both of these is the subtle mind of clear light which shares the nature of a Buddha’s Wisdom Body. All we have to do is learn to transform these ordinary elements into their pure natures. Then buddhahood naturally comes into our hands.
