Om Namo Bhagavate Vasudevaya
ॐ नमो भगवते वासुदेवाय
oṃ namo bhagavate vāsudevāya
oṃ: The eternal source-sound-vibration of creation.
namo: (Same as "namaha") To honor or solute. "All glory to..."
bhagavate: Addressive case of Bhagavan, as in "I bow to the lord." Bhagavan mean "Lord" in the most spiritual, sacred sense of the word.
vāsudevāya: Addressive case of "vāsudeva," a name for Krishna, whose father was Vasudeva. Elongating the first "a" in sanskrit turns it into "the son of," meaning that "vāsudeva" is the "son of vasudeva."
"A Vedic style chant, complete with 'Om', the universal YES!, and 'Namo', which tells us what we need to do: place our heads down towards mother earth and humbly remember Bhagavate (God) who is filled with all virtues. Then, with grace, we can come face to face with Vasudeva, the holder of all things." ~ Shyamdas
"I shall ever look to the maintenance of the material and spiritual welfare of those who think of Me constantly and worship Me with single-pointed devotion." ~ Bhagavad Gita
"Om Namo Bhagavate Vasudevaya is a twelve syllable mantra of Krishna or Vishnu, known as a liberating mantra for attaining spiritual freedom. This is the principal mantra of the Vedic scripture 'Srimad Bhagavatam,' and can also be found in Vishnu Purana." ~ wikipedia
