"In the ancient system of initiation, the truth seeker must pass through a second birth, and those who attained this exalted state were known thereafter as "the twice born." Only one who has been born again can understand the mysteries of heaven. This new birth, however, is not attained by merely joining a sect. It must be personally earned through a complete regeneration of character and conduct." [Manly Palmer Hall]
"Through me you will die while still living in your body, to be reborn into an immortal existence:
Thus do I stand before you here to-day visible, as I have always stood invisible beside you in the hour of death. When you shall have passed my threshold you will enter those kingdoms which else would have opened to you only at physical death. You will enter them with full knowledge, and henceforth, when you wander outwardly visible upon the earth, you will also move through the kingdom of death, which is the kingdom of eternal life. I am indeed the angel of Death; yet at the same time I am the bringer of an imperishable higher life. Through me you will die while still living in your body, to be reborn into an immortal existence. The kingdom that you now enter will introduce you to beings of a superhuman kind, and in that kingdom happiness will be your lot."
[Rudolf Steiner, Initiation and Its Results, 1910, p. 151.]
