Reality is a full-spectrum, multi-dimensional consciousness from the most subtle dimensions to those which are the most dense. Consciousness creates the Relative Field as the arena of all experience, which in truth is nothing less than the experience of itself. At the most subtle level of reality, the relative polarities are unified, and both polarities, Being and Becoming, are experienced as the same consciousness. Such is the experience of unified consciousness or oneness.
The above quotation refers to this state of unified consciousness insofar as the polarities of ending and beginning are not separate from each other but are experienced simultaneously. It is therefore a truthful statement from a subtle dimensional perspective.
