OM
The three letters of ‘
AUM’ ‘A’, ‘U’, and ‘M’ have been variously interpreted in different scriptures. The
Vayu Purana contends that ‘A’-sound is connotative of
Vishnu, ‘U’-sound signifies
Shiva, and ‘M’-sound,
Brahma. Some scholars hold that ‘A’ represents ‘Adimatva’ – beginning; ‘U’, ‘utkarsha’ – progress; and, ‘M’, ‘miti’ – limit or dissolution; that is, three letters of ‘AUM’ represent the power that creates, develops or sustains, and dissolves, and such power is no other than
God Himself. Under this view
God and ‘
AUM’ are identical, God’s all names are contained in ‘
AUM’, and ‘AUM’ ‘
AUM’ as corresponding to three basic elements created by primary explosion, namely,
body-mind-spirit.
"All those activities which people start with uttering the syllable OM do not fail to bear fruit."
(Shankaracharya's Commentary on the Taittriya Upanishad 1.8.1)
