This is a twelve syllable mantra of Krishna, or Vishnu. It is known as a Mukti (liberation) mantra and a spiritual formula for attaining freedom.
Everybody should recite “Om Namo Bhagavate Vasudevaya” mantra daily whenever possible so that I will stand by them. I respond to the call of the heart immediately and invariably. See me in your duties. I am committed to those who are committed to their duties. Believe in putting faith in me and make me your own.
