1.Aum (also Om, ) is the most sacred syllable in Hinduism, in which Vedic tradition it originated. The syllable is sometimes referred to as the "Udgitha" or "pranava mantra" (primordial mantra); not only because it is considered to be the primal sound, but also because most mantras begin with it. As a seed syllable (bija), it is also considered holy in Esoteric Buddhism.
2.Gods and Goddesses are sometimes referred to as Aumkar, which means Form of Aum, thus implying that they are limitless,
3.Creation (Brahma)- Preservation (Vishnu)- Destruction (Shiva) into Brahman
Waking- Dreaming- Dreamless Sleep into Turiya (transcendental fourth state of consciousness)
Rajas (activity, heat, fire)- Tamas (dullness, ignorance, darkness)- Sattva (purity, light, serenity/shanti) into Brahman
Body, Speech and Mind into Oneness
4."Aum" can be seen as Sri Ganesh, whose figure is often represented in the shape of Aum. He is thus known as Aumkar (Shape of Aum). Sri Nataraja, or the Hindu god 'Shiva' dancing his dance of destruction, is seen in that popular representation mirroring the image of Aum. It is said to be the most perfect 'approximation' of the cosmic existence within time and space, and therefore the sound closest to Truth. "The First Word Om (Aum) It is also called Pranav because its sound emanates from the Prana (vital vibration), which feels the Universe. The scripture says "Aum Iti Ek Akşara Brahman" (Aum that one syllable is Brahman).
5.In the Rig-Veda we find the following information; "One who chants om, which is the closest form of Brahman, approaches Brahman. This liberates one from the fear of the material world, therefore it is known as tarak Brahman."
6.Aum takes the form of Gayatri, then Veda and Vedanta sutra; then it takes the shape of Srimad Bhagavatam and the lila, the divine pastimes, of the Lord."
