The Upanishads are commonly referred to as Vedānta. Vedanta has been interpreted as the "last chapters, parts of the Veda" and alternatively as "object, the highest purpose of the Veda". The concepts of Brahman (ultimate reality) and Ātman (soul, self) are central ideas in all of the Upanishads,and "know that you are the Ātman" is their thematic focus. Along with the Bhagavad Gita and the Brahmasutra, the mukhya Upanishads (known collectively as the Prasthanatrayi) provide a foundation for the several later schools of Vedanta, among them, two influential monistic schools of Hinduism.
