Cutting Through the Three Times states:

United as one, everything is the basic space of oneness. Oneness is without origination-the unborn basic space of phenomena. The magical displays that are born within unborn basic space are thoroughly indeterminate and completely unrestricted. In awareness, the ultimate heart essence of enlightenment, there is no holding to extreme views, but rather freedom from bias based on characteristics. There is no conclusion to be reached through theories of language or knowledge. It is beyond characterization,  can be neither affirmed nor denied, neither increases nor decreases, and neither comes nor goes. Given total purity in the supreme spaciousness of spontaneous evenness, there is uninterrupted openness, free of all extremes or bias.
