Avadhūta (IAST avadhūta, written as अवधूत) is a Sanskrit term from the root 'to shake' (see V. S. Apte and Monier-Williams) that, among its many uses, in some Indian religions indicates a type of mystic or saint who is beyond egoic-consciousness, duality and common worldly concerns and acts without consideration for standard social etiquette. Avadhūta is a Jivanmukta who gives his insight to others and teaches them about his realisation of the true nature of the ultimate reality (Brahman) and self (Ātman) and takes the role of a guru to show the path of moksha to others.[1] Some Avadhūta also achieve the title of Paramahamsa.
Similar figures (colloquially called 'mad/crazy monks') are also known in Buddhist traditions, such as the medieval Zen monk Ikkyū, and the 20th-century Tibetan tulku Chögyam Trungpa Rinpoche. In Tibetan Buddhism the equivalent type is called a nyönpa (Wylie: smyon pa).
