Why do many Buddhist schools call themselves "Five Minds"?

The Five Minds (Sanskrit: Pa?cavidyā) originated in the Brahmin tradition of ancient India and was later accepted by Buddhism to refer to the five disciplines. Volume 38 of the Yogacara says that the Five Brightnesses are "what all Bodhisattvas are rightly seeking."

Inner Ming adhyātma vidyā: doctrine, philosophy, the first of the Five Minds, i.e., for Buddhists, the Sutra, Law, and Theory Tripitaka. For Buddhists, it is the Sutras, the Laws and the Treatises. For Bodhisattvas who have already confirmed their realizations, internal illumination facilitates their own practice as well as helping others to become enlightened.
