#Thread on decoding the ॐ/AUM/OM
AUM is made up of 3 syllables: A, U, & M, or, phonetically, “aaah,” “oooh,” & “mmm.” A is the first of the guttural sound, so it is the very first sound that human can utter, M is the last of the labial sounds and
U is the sound produced by rolling the wind over the whole of the tongue. Hence the conjunction of these 3 primary sounds can be comprehended to contain the rudiment of all sounds that human can ever give utterance to and so it can be taken as the fittest sound symbol of Brahman.
According to Taittiriya Upanishad 1.8.1-
MnOm is Brahman. Om is everything here.
At a physical level, the Aum syllable addresses the whole of the human sound instrument: we open the mouth (a), move the lips closer to each other (u) & then close the mouth (m).
This activates the larynx fully. ‘A’ resonates in the stomach and chest, ‘u’ in the throat and chest and ‘m’ in the nasal cavity, skull and brain. By chanting Aum we move the energy from the abdomen up to the brain.
Moreover, the syllable AUM represents several important triads:
Worlds - Earth, Atmosphere, and Heaven; Major Hindu Gods - Brahma, Vishnu, and Shiva; Gunas: Tamas, Rajas and
Sattva; Sacred Vedic scriptures - Rg, Yajur, and Sama; Actions: Creation, Preservation, and Destruction; Time: Past, Present, and Future;
