Brahman
In Hinduism, Brahman connotes the highest Universal Principle, the Ultimate Reality in the universe.P. T. Raju (2006), Idealistic Thought of India, Routledge,, page 426 and Conclusion chapter part XII In major schools of Hindu philosophy, it is the material, efficient, formal and final cause of all that exists.For dualism school of Hinduism, see: Francis X. Clooney (2010), Hindu God, Christian God: How Reason Helps Break Down the Boundaries between Religions, Oxford University Press,, pages 51–58, 111–115;For monist school of Hinduism, see: B. Martinez-Bedard (2006), Types of Causes in Aristotle and Sankara, Thesis – Department of Religious Studies (Advisors: Kathryn McClymond and Sandra Dwyer), Georgia State University, pages 18–35 It is the pervasive, genderless, infinite, eternal truth and bliss which does not change, yet is the cause of all changes. Brahman as a metaphysical concept is the single binding unity behind diversity in all that exists in the universe. Brahman is a Vedic Sanskrit word, and it is conceptualized in Hinduism, states Paul Deussen, as the "creative principle which lies realized in the whole world". Brahman is a key concept found in the Vedas, and it is extensively discussed in the early Upanishads.Stephen Philips (1998), Routledge Encyclopedia of Philosophy: Brahman to Derrida (Editor; Edward Craig), Routledge,, pages 1–4 The Vedas conceptualize Brahman as the Cosmic Principle. In the Upanishads, it has been variously described as Sat-cit-ānanda (truth-consciousness-bliss) and as the unchanging, permanent, highest reality. Brahman is discussed in Hindu texts with the concept of Atman (Soul, Self), personal, impersonal or Para Brahman, or in various combinations of these qualities depending on the philosophical school. In dualistic schools of Hinduism such as the theistic Dvaita Vedanta, Brahman is different from Atman (soul) in each being.Michael Myers (2000), Brahman: A Comparative Theology, Routledge,, pages 124–127 In non-dual schools such as the Advaita Vedanta, Brahman is identical to the Atman, is everywhere and inside each living being, and there is connected spiritual oneness in all existence.Arvind Sharma (2007), Advaita Vedānta: An Introduction, Motilal Banarsidass,, pages 19–40, 53–58, 79–86.
