1. All aspects of speech are believed to have come forth from this word. ‘Om’ is an evocation of the universal soul - The Brahman.OM is also pronounced as AUM.

2. This mystic symbol is also the most powerful Hindu mantra . It is composed of five elements: the syllables a, u, m, the dot or bindu and sound (nada), and is revered as the representative of the gods. Om first appears in the Upanishads  as a mystic monosyllable and is regarded as the seed or basis of all mantras.

3. 'A' is the root sound produced without touching any part of the tongue or palate, 'm' represents the last sound in the series, being pronounced by closed lips. Between these two sounds exist all others. The three constituents of Om also represent the deities of the Trimurti : 'a' represents Brahma,  the creator, who introduces the soul into the cycle of life;  'u' Vishnu, the sustainer, who helps the soul participate in the cycle of life; and 'm' Mahesh , the destroyer, who liberates the soul from the cycle of life . Hence it also represents creation, preservation and destruction.

4. Meditation on this sacred syllable is said to satisfy every need and leads to liberation.It is also said that AAAH is the most natural sound that issues from the human larynx. This is evident when a man cries out naturally in extreme pain, anger or fear. When emotions reach an extreme pitch the articulate sounds evolved by man are not the ones that are heard, but the syllable natural to man which is AAAH   is quite familiar to OM . It occurs in every prayer. Invocation to most gods begin with this syllable. For instance we have Om Namaha Shivaya, Hari Om, Om Shanti etc.
