Part 1
We are meant to consciously serve, moment to moment, the Light of Life that ceaselessly introduces us to ourselves, not live in unconscious servitude to the nature of that (passing) character to which we are introduced.
Part 2
When living within the limits of what is known is also realized as being the limitation of your spiritual possibilities, then there is no recourse other than to depart the safety of all that you have been in favor of discovering all that you are yet to be.
