The syllable OM is an ancient Sanskrit letter first found in the Vedas, originating between 1500 – 1200 BC. A collection of Vedic Sanskrit hymns, they were sung in praise of the Divine. They were not written out at first but were vibrated into existence using human speech.
These mantras are more about the vibrational content than the meaning. Frawley again: “Om is the Word of God.” The sound OM is a vibration from which all the manifest universe emanates. Form and creation comes from vibration. OM is the most elemental of vibrations.
