nondualism

Nondualism, also called non-duality, "points to the idea that the universe and all its multiplicity are ultimately expressions or appearances of one essential reality." 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:

• advaya, the nonduality of conventional and ultimate truth, or relative and Absolute reality:

• Buddhist Madhyamaka, which says there is no absolute, transcendent reality beyond our everyday reality;
• Chinese Mahayana, but also neo-Vedanta, which says that there is no absolute difference between the relative world and "absolute" reality;

• advaita, the non-difference of Atman and Brahman or the Absolute; it is best known from Advaita Vedanta, but can also be found in Kashmir Shaivism, popular teachers like Ramana Maharshi and Nisargadatta Maharaj, and in the Buddha-nature of the Buddhist tradition;
• "nondual consciousness", the non-duality of subject and object; this can be found in modern spirituality.
