Mark how to know yourself. To know himself a man must ever be on the watch over himself, holding his outer faculties. This discipline must be continued until he reaches a state of consciousness. The object is to reach a state of consciousness — a new state of oneself. It is to reach now, where one is present to oneself. What I say unto you I say unto all: Be awake.

Meister Eckhart (circa 1260 – 1328)
