Philosophy of mind
Dualism is a set of views about the relationship between mind and matter (or body). It begins with the claim that mental phenomena are, in some respects, non-physical. One of the earliest known formulations of mind–body dualism was expressed in the eastern Sankhya and Yoga schools of Hindu philosophy (c. 650 BCE), which divided the world into purusha (mind/spirit) and prakriti (material substance). Specifically, the Yoga Sutra of Patanjali presents an analytical approach to the nature of the mind.
Dualism (Indian philosophy)
While Western philosophical traditions, as exemplified by Descartes, equate mind with the conscious self and theorize on consciousness on the basis of mind/body dualism; some Eastern philosophies provide an alternate viewpoint, intimately related to substance dualism, by drawing a metaphysical line between consciousness and matter — where matter includes both body and mind.
