According to the Ancient Philosophy of the Vedas, ‘Aum’ is the secret and the highest name of God; it is composed of three letters, A, U, M. This one name comprises many other names of God. Thus, briefly:- A stands for massive or grand, Fire and Universe, etc. . U stands for the golden womb, air and splendor, etc. M stands for lord, Sun and consciousness, etc. Vedas and other true scriptures, that whatever they treat of God; all these names stand for Him.
There are no other gods. The multitude of names signify not different Divine Beings but different aspects of one Absolute Existence or God.
