Parabrahma refers to the supreme being in Hinduism, represented by the sacred sound "Aum". It is all-pervasive and omnipotent. Hindus believe that all beings and things in the universe are part of a single family, and their highest prayer is for the well-being and happiness of all. Hinduism accepts the oneness of Parabrahma but also the diversity of beliefs and visions among people. It provides freedom of thought and respects all religions. Life is seen as a spiritual journey towards self-actualization through reincarnation and evolution of knowledge and experience over multiple lifetimes.
