This background medium is equivalent to the Tao, the Buddhist Nirvana, the Godhead. In it all possibilities are realized insofar as they are internally coherent.
Reality is, essentially, a negation or differentiation of this homogeneous, undifferentiated medium (recall the Hindu/Tantrum dichotomy of purusha and maya, Shiva and Shakti, the eternal and unchanging contrasted with the temporal and in flux). Thus, for objects, for space and time to meaningfully exist, there must be some medium to impart coherence to all this diversity of form, or else these objects would exist in their distinct realities and there would be no recognizable universe of which to speak of.
The Absolute imparts ontological coherence, perceptual stability. Even the skeptic cannot doubt the fact of his doubting. The rest of reality is the play and flux of form, the "waves" on the "ocean" of this medium. Being vs. Becoming.
The Absolute is the source of all that is Good and free. Reality exists to actualize itself, to maximize its"coherency", ie participating more and more in the nature of the Absolute, since the other direction is dissolution and non-existence.
The Good is what is beneficial to the system. We are all subsystems in a master system, a microcosm of a macrocosm. Evil is what is harmful to the system in favor of the gratification of one subsystem. There are no moral qualities, only objective states of actualization and purity, or mixture and dissipation.
Death is the recycling of one's components in this closed system. God is the consciousness of the system in its totality. "Divine grace", Love, the Sacred, everlasting life, these are all qualities of those subsystems which embody the eternal nature of the master system, ie God.
