The Advaita Vedanta describes my experience:
"Advaita Vedānta literally, 'non-duality') is a school of Hindu philosophy, and is a classic system of spiritual realization in Indian tradition. The term Advaita refers to the idea that Brahman alone is ultimately real, the phenomenal transient world is an illusory appearance (Maya) of Brahman, and the true self, Atman, is not different from Brahman."
The Atman within each Being is one with Brahman. Everything else is an illusion.
Every word, label, and name is a belief, a construct, a fabrication in the world of form. "Nonduality" is only a pointer. Language is not the thing it tries to describe. Ultimate reality has no language; it simply is. The finger pointing at the moon is not the moon.
