The tree of life, the axis mundi is the central point, the pole around which all revolves. The central point of the world is the point where stillness and movement are together. Movement is time, but stillness is eternity. Realizing how this moment of your life is actually a moment of eternity, and experiencing the eternal aspect of what you are doing in the temporal experience -- this is the mythological experience.
What prompts this surrender -- this total turning to God in self-donation and makes it possible is the realistic recognition that my very life and being is a gift of love. It is a recognition which becomes experiential in contemplative prayer, in a "knowing" that is beyond knowledge; it is the graced knowledge of love. Only such a gift can make unconditional self-surrender possible, for it is an experience of the unconditional love of a person,a personal God. It is such a recognition that breaks forth joyously in Daniel Berrigan's "All, all is gift. Give it away. Give it away."
