The Alan Watts and Shirley McClain view of spirituality helped to shed a little light into an otherwise closed modern mind—yet a mind always open to materialism and new ways of presenting it. The controversy between spiritualism and materialism was never well understood or well tolerated. Still, the spirit (Geist) is able to make its way through the barriers of materialism. This was the advent of the term non-local reality (the real second coming).
Jumping ahead, realism and locality are both useful but false. Oddly, physics doesn't contradict this claim (read Donald D. Hoffman's book, The Case Against Reality). We are free to conclude that spirit has defeated materialism. Surprisingly, what now lies before us as appearance or māyā has its origin in the non-appearing, the transcendent. This is what the Buddha meant when he taught the following:
“There is, monks, an unborn, unbecome, unmade, unconditioned. If, monks there were not that unborn, unbecome, unmade, unconditioned, you could not know an escape here from the born, become, the made, and conditioned. But because there is an unborn, unbecome, unmade, unconditioned, therefore you do know an escape from the born, become, made, and conditioned” (Tatiyanibbānapaṭisaṃyuttasutta).
The Buddha's awakening granted him supreme knowledge that local realism is not fundamental; moreover that it's illusory. The fact is, physical objects do not have actual definite values or own-nature (svabhāva). Locality is the assumption that physical things in their own way are 'sort of' true' in a relative way. Realism has survived a long time while the world of spirit (non-locality) has been greatly diminished as a result. But the prison break has already started. The llusion of separation, a duality (dvaya), has never been other than an illusion.
How to escape from the tyranny of realism is what the Buddha actually discovered. As expected, the other part of Buddhism is about samsara/saṃsaraṇa (√saṃsṛ) our continuous re-involvement in suffering under the mistaken belief (avidya) that appearances are primary and not secondary. Without first awakening to primary, base reality (Zen's kenshõ) which is non-local we are stuck in samsara. Even death falls within the domain of samsara. Continuous re-suffering is always the case with samsara.
