An interpretation of Om

“OM, when considered as one letter, uttered by the help of one articulation, is the symbol of the Supreme Spirit. But when considered a trilateral word consisting of a, u, m, it implies the three Vedas, the three states of human nature, the divisions of the universe, and the three deities – Brahma, Vishnu and Shiva, agents in the creation, preservation and destruction of this world; or, properly speaking, the three principal attributes of the Supreme Being personified in those three deities. In this sense it implies, in fact, the universe controlled by the Supreme Spirit” - Raja Ram Mohan Roy
