Nondualism

In spirituality, nondualism, also called non-duality, means "not two" or "one undivided without a second".[1][2] Nondualism primarily refers to a mature state of consciousness, in which the dichotomy of I-other is "transcended", and awareness is described as "centerless" and "without dichotomies". Although this state of consciousness may seem to appear spontaneous,[note 1] it usually follows prolonged preparation through ascetic or meditative/contemplative practice, which may include ethical injunctions. While the term "nondualism" is derived from Advaita Vedanta, descriptions of nondual consciousness can be found within Hinduism (Turiya, sahaja), Buddhism (emptiness, pariniṣpanna, nature of mind, rigpa), Islam (Wahdat al Wujud, Fanaa, and Haqiqah) and western Christian and neo-Platonic traditions(henosis, mystical union).

The Asian ideas of nondualism developed in the Vedic and post-Vedic Upanishadic philosophies[3] as well as in the Buddhist traditions.[4] The oldest traces of nondualism in Indian thought are found in the earlier Hindu Upanishads such as Brihadaranyaka Upanishad, as well as other pre-Buddhist Upanishads such as the Chandogya Upanishad, which emphasizes the unity of individual soul called Atman and the Supreme called Brahman. In Hinduism, nondualism has more commonly become associated with the Advaita Vedanta tradition of Adi Shankara.[5]

In the Buddhist tradition non-duality is associated with the teachings of emptiness (śūnyatā) and the two truths doctrine, particularly the Madhyamaka teaching of the non-duality of absolute and relative truth,[6][7]and the Yogachara notion of "mind/thought only" (citta-matra) or "representation-only" (vijñaptimātra).[5]These teachings, coupled with the doctrine of Buddha-nature have been influential concepts in the subsequent development of Mahayana Buddhism, not only in India, but also in East Asian and Tibetan Buddhism, most notably in Chán (Zen) and Vajrayana.
