Mind-Only (sems tsam pa), Chittamatra. A Mahayana school of Buddhist philosophy propagated by the great master Asanga and his followers. Founded on the Lankavatara Sutra and other scriptures, its main premise is that all phenomena are only mind, i.e. mental perceptions that appear within the all-ground consciousness due to habitual tendencies. Positively, this view relinquishes the fixation on a solid reality. Negatively, there is still clinging to a truly existing 'mind' within which everything takes place.
