Lord Brahma is the Hindu God of creation. Nada is the sound created for healing and empowerment. Vibrations produced from chants help in stilling a restless mind and in dispelling negative energies and bringing in positive ones. These sound vibrations are the beeja (seed) mantras that have a direct effect on our chakras. The power of the mantra comes from the direct vibrations they produce on the body and not from the meaning of the syllables.
