context_page_description: In spirituality, nondualism, also called non-duality, means "not two" or "one undivided without a second". 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, 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, Buddhism, Islam and western Christian and neo-Platonic traditions.
  The Asian ideas of nondualism developed in the Vedic and post-Vedic Upanishadic philosophies as well as in the Buddhist traditions. 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.
context_section_description: According to Kameshwar Nath Mishra, one connotation of advaya in Indic Sanskrit Buddhist texts is that it refers to the middle way between two opposite extremes (such as eternalism and annihilationism), and thus it is "not two".
  
  One of these Sanskrit Mahayana sutras, the Vimalakīrti Nirdeśa Sūtra contains a chapter on the "Dharma gate of non-duality" (advaya dharma dvara pravesa) which is said to be entered once one understands how numerous pairs of opposite extremes are to be rejected as forms of grasping. These extremes which must be avoided in order to understand ultimate reality are described by various characters in the text, and include: Birth and extinction, 'I' and 'Mine', Perception and non-perception, defilement and purity, good and not-good, created and uncreated, worldly and unworldly, samsara and nirvana, enlightenment and ignorance, form and emptiness and so on. The final character to attempt to describe ultimate reality is the bodhisattva Manjushri, who states:
  It is in all beings wordless, speechless, shows no signs, is not possible of cognizance, and is above all questioning and answering. 
  Vimalakīrti responds to this statement by maintaining completely silent, therefore expressing that the nature of ultimate reality is ineffable (anabhilāpyatva) and inconceivable (acintyatā), beyond verbal designation (prapañca) or thought constructs (vikalpa). The Laṅkāvatāra Sūtra, a text associated with Yogācāra Buddhism, also uses the term "advaya" extensively.
  In the Mahayana Buddhist philosophy of Madhyamaka, the two truths or ways of understanding reality, are said to be advaya (not two). As explained by the Indian philosopher Nagarjuna, there is a non-dual relationship, that is, there is no absolute separation, between conventional and ultimate truth, as well as between samsara and nirvana. The concept of nonduality is also important in the other major Indian Mahayana tradition, the Yogacara school, where it is seen as the absence of duality between the perceiving subject (or "grasper") and the object (or "grasped"). It is also seen as an explanation of emptiness and as an explanation of the content of the awakened mind which sees through the illusion of subject-object duality. However, it is important to note that in this conception of non-dualism, there are still a multiplicity of individual mind streams (citta santana) and thus Yogacara does not teach an idealistic monism.
  These basic ideas have continued to influence Mahayana Buddhist doctrinal interpretations of Buddhist traditions such as Dzogchen, Mahamudra, Zen, Huayan and Tiantai as well as concepts such as Buddha-nature, luminous mind, Indra's net, rigpa and shentong.
