Indian Philosophy. Sacred OHM.

The word Ohm has about a hundred meaning. One of them is Welcome to God.
‘Ohm’ can be repeated aloud, in whispers or silently. The silent repetition is most effective to still our mind and connect us to God. As we repeat, if we can feel the humming vibrations of this syllable in every cell of our body.
And when we are aware that this sacred syllable also represents the Unity of God’s manifestation, the repetition helps us experience the oneness that is inherently present everywhere. The vibrations unite us with the ultimate being.
OHM is not a word but rather an intonation, which, like music, transcends the barriers of age, race, culture and even species. OHM is made up of three letters, aa, au and ma which, when combined together, make the sound Aum or OHM.
OHM is believed to be the basic sound of the world and to contain all other sounds. OHM is a mantra, or prayer in itself. If repeated with the correct intonation, it can resonate throughout the body so that the sound penetrates to the center of our being, the atman or the soul.
There is harmony, peace and bliss in this simple but deeply philosophical sound.
By vibrating the sacred syllable Ohm, the supreme combination of letters, if one thinks of the Ultimate Personality of God, he will certainly reach the highest state of "stateless" eternity.
OHM is a sacred syllable that is considered to be the greatest of all the mantras, or sacred formulae.
The syllable Ohm is composed of the three sounds a-u-m, which represent several important triads: the three worlds of earth, atmosphere, and heaven.
It belongs to, Brahma, Vishnu, and Shiva. OHM is the source of the three Vedas, Rig Veda, Yajur Veda, and Sama Veda. OHM mystically embodies the essence of the entire universe. OHM is uttered at the beginning and end of all prayers, chants, and meditation and is freely used in Buddhist and Jain Sikh scriptures also.
From the 6th century, the written symbol OHM is used to mark the beginning of a text in a manuscript or an inscription. OHM is discussed in a number of the Upanishads, which are the texts of philosophical speculation, and it forms the entire subject matter of one Universe. OHM is used in the practice of Yoga and is related to techniques of auditory meditation.
