Meaning of OM
OM is considered to be the ‘primordial sound’. Even before the material creation came into existence there was only the natural humming energy which resembled the sound of OM. Today, we know that one form of energy can be converted to another form – electricity to sound, electricity to heat, heat to electricity etc. According to the famous equation by Einstein – E=mc2, all matter is nothing but waves of energy. So, when the ‘powers that be’ decided to create this material universe, they were able to use the ever-present humming sound vibration of OM to manifest this creation. This same vibration continues to exist all around us and even inside us. The inner sound is given the name "antar-naada" (the inner sound) which can be heard when we can tune in to our pure inner self.
The OM mantra has been mentioned in many of the ancient texts related to yoga. In many of the Upanishads, it is revered as representing everything that is manifest and yet has its roots in the unmanifest. The Mandukya Upanishad (MU), in particular, is fully devoted to the discussion of OM. In the Upanishads, OM is mentioned as being the same as Brahman (the supreme consciousness).
