Choiceless awareness is posited in philosophy, psychology, and spirituality to be the state of unpremeditated, complete awareness of the present without preference, effort, or compulsion. The term was popularized in mid-20th century by Indian philosopher Jiddu Krishnamurti; the concept is a central theme in his philosophy. Similar or related concepts had been previously developed in several religious or spiritual traditions. The term, or others like it, has also been used to describe traditional and contemporary meditation practices, both secular and religious. By the early 21st century, choiceless awareness as a concept or term had appeared in a variety of fields, including neuroscience, therapy, and sociology, as well as in art. However, Krishnamurti's approach to the subject was unique, and differs from both prior and later notions.
