Non-dualism

Nondualism, also called non-duality, means "not two" or "one undivided without a second". It is a term and concept used to define various strands of religious and spiritual thought. It is found in a variety of Asian religious traditions and modern western spirituality, but with a variety of meanings and uses. The term may refer to:

The nondualism idea developed in the Vedic, post-Vedic Hindu and the Buddhist traditions. The oldest traces of nondualism in Indian thought is found as Advaita in the Brihadaranyaka Upanishad, as well as other pre-Buddhist Upanishads such as the Chandogya Upanishad. The Buddhist tradition added the teachings of śūnyatā; the two truths doctrine, the nonduality of the absolute and the relative truth, and the Yogachara notion of "mind/thought only" (citta-matra) or "representation-only" (vijñaptimātra).Vijñapti-mātra and the two truths doctrine, coupled with the concept of Buddha-nature, have also been influential concepts in the subsequent development of Mahayana Buddhism, not only in India, but also in China and Tibet, most notably the Chán (Zen) and Dzogchen traditions. In Hinduism, nondualism has more commonly become associated with the Advaita Vedanta tradition of Adi Shankara.

The western origins are situated within Neo-Platonism and Western esotericism, especially Swedenborgianism, Unitarianism, Transcendentalism and the idea of mystical experience as a valid means of knowledge of a transcendental reality. Universalism and Perennialism are another important strand of thought, as reflected in various strands of modern spirituality, New Age and Neo-Advaita.
