According to the Advaita (non-dualist) Vedanta, the entire world is a Maya or illusion. There is no existence except Brahman (God). It is God that evolves and involves. When IT evolves, Big Bang like expansion with the primordial sound ‘Aum’ happens. At the time of ITS involution/dissolution, Big Crunch will result and all the creations will shrink back into their ultimate source. This evolution and involution go on cyclically. This, according to Vedantic tradition, is the ultimate reality, and the rest illusory. A logical corollary deduced from the above postulate is that the consciousness that helps in uniting souls is real and the one that divides is unreal. Love unites. Therefore, love helps in perception of the reality. Hatred divides. Therefore, hatred drifts us from the reality.
