Om

Om is the supreme mantra. Actually there is no translation for Om, but we can say if we need to explain this mystic sound, that it is the sound of creation, or it is the vibration of the manifestation of creation. First there was Om, and then the Universe came. Any vibration at the end will lead back to Om.
Om is the activation of the 3rd eye centre, the point between the eyebrows; this place is the Ajna chakra, a chakra being an energy centre. Thus when the Ajna chakra is activated it in turn activates all the other charkas in the body; the cells become activated and rejuvenated.
By chanting Om it is said we can heal the whole body.
Om is a combination of sounds –
A U M
Each sound representing the different states of consciousness that we go through each day, the waking state, dream state and deep sleep state. After this there is silence, silence cannot be written.
Om is all sounds, all vibrations, all languages and all mantras.
The sound should begin from the navel, with a deep, harmonious vibration, which gradually manifests itself at the upper part of the nostrils.
The universe has come from Om, rests in Om and dissolves in it.
With that I say Om.
