There are thousands of nonduality books and many nonduality teachers discussing Advaita Vendanta, Taoism, Zen, The Perennial Wisdom Teachings, and Oneness.
I’ve come across very few nonduality teachers and writers willing to point towards the fantasy of a personal self. Even the writings attributed to Nisargadatta, Lao Tzu, and Krishnamurti are words attempting to reflect the wordless and incomprehensible message these sages appeared to point towards. They grasped the paradox of what is appearing and warned against swallowing concepts and words.
Words, oral or written, cannot ever describe what is…it cannot be comprehended with the brain. Some measure of Mystery and Grace seems to peel the untruth from the human eye and heart to reveal what has never not been here, now. the incomprehensible mystery of what is.
