Hinduism unfolds the verity that before even the creation of absolute reality, "Brahman" thought, "I am only one - May I become many". This definitive truth, this particular realization gave birth to an immense vibration, and finally a sound, which was even intense than the humming of a billion bees. This sound was the "Om" and is the first sound of Brahman, which eventually set creativity into motion.

From the remote past of the ancient rimes "Om" is therefore considered as one of the most sacred syllable in Hinduism, in which Vedic tradition is originated. It is reckoned as the primal sound and most of the mantras begin with it. Due to these reasons the syllable is sometimes referred to as the "Udgitha" or "Pranava mantra". Om has been seen first in the Vedic scriptures of Hinduism. The om symbol`s left part is also a component of some Devanagari letters, where it means "this syllable has no initial consonant".

There are four main levels of consciousness outlined in the OM Mantra, along with three transition levels, which is a total of seven levels. Each of these is experienced on the inner journey of meditation and contemplation. These levels of consciousness are realities that exist universally. The underlying principles are extremely useful for all seekers in purifying or clearing the mind, and seeking the direct experience of deeper truths.

OM being the first or last sound in the whole mantra is very often used in conjunction with other mantras. Often these mantras refer to a specific deity or name of God. Some consider that the OM refers to only one God while others believe differently. Om mantra can be used differently as there are varieties of ways of using it but the vibration of Om will always be experienced on the inner journey. OM Mantra is presented as a means of contemplation and meditation, which pierces the three levels of reality and consciousness, revealing the fourth, which permeates the other three.

The concept that goes with OM is the one-ness or entirety of the universe. Chanting mantra aloud can be a very enjoyable and useful process it can be done alone on with a group of people. After sometime the process turns inward, and the chanting is done in the inner silence. It will naturally shift in speed, sometime moving very fast, or will naturally move very slowly. It can be beneficial to use mala or counting beads at the beginning stage of using mantra. Mantra is somewhere used as a name of god from within their religion, or as given by a teacher.
