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.
Nondualism
The "New Age movement" is a Western spiritual movement that developed in the second half of the 20th century. Its central precepts have been described as "drawing on both Eastern and Western spiritual and metaphysical traditions and infusing them with influences from self-help and motivational psychology, holistic health, parapsychology, consciousness research and quantum physics".
The New Age aims to create "a spirituality without borders or confining dogmas" that is inclusive and pluralistic. It holds to "a holistic worldview", emphasising that the Mind, Body and Spirit are interrelated and that there is a form of monism and unity throughout the universe. It attempts to create "a worldview that includes both science and spirituality" and embraces a number of forms of mainstream science as well as other forms of science that are considered fringe.
