Avadhūta (IAST avadhūta, written as अवधूत) is a Sanskrit term from the root ’to shake’ 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
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)
