A Beautiful Mind

As the cross is to Christians, the Om is to Hindus. It is made up of three Sanskrit letters, aa, au and ma which, when combined, make the sound Aum or Om. The most important symbol in Hinduism, it occurs in every prayer and invocation to most deities begins with it.
By sound and form, AUM symbolizes the infinite Brahman (ultimate reality).

A stands for Creation
U stands for Preservation
M stands for Destruction or dissolution
This is representative of the Trinity of God in Hindu dharma (Brahma, Vishnu and Shiva).The three portions of AUM relate to the states of waking, dream and deep sleep.The three letters also indicates three planes of existence, heaven (swarga), earth (martya) and netherworld (patala).
All the words produced by the human vocal organ can be represented by AUM. A is produced by the throat, U & M by the lips.In the Vedas, AUM is the sound of the Sun, the sound of Light. It is the sound of assent (affirmation) and ascent.

Even the word 'Amen' used by Christians to conclude a prayer seems to be akin to Om.

The syllable Om occurs even in English words having a similar meaning, for instance, 'omniscience'.And so they say...."The world exists in Om and dissolves in Om."
