: I compare human life to a large Mansion of Many Apartments, two of which I can only describe, the doors of the rest being as yet shut upon me - The first we step into we call the infant or thoughtless Chamber, in which we remain as long as we do not think - We remain there a long while, and notwithstanding the doors of the second Chamber remain wide open, showing a bright appearance, we care not to hasten to it; but are at length imperceptibly impelled by awakening of the thinking principle - within us - we no sooner get into the second Chamber, which I shall call the Chamber of Maiden-Thought, than we become intoxicated with the light and the atmosphere, we see nothing but pleasant wonders, and think of delaying there for ever in delight: However among the effects this breathing is father of is that tremendous one of sharpening one's vision into the nature and heart of Man — of convincing one's nerves that the World is full of misery and Heartbreak, Pain, sickness and oppression — whereby This Chamber of Maiden Thought becomes gradually darken'd and at the same time on all sides of it many doors are set open - but all dark - all leading to dark passages — We see not the balance of good and evil. We are in a Mist - We are now in that state — We feel the burden of the Mystery.
