The meaning of the Omnipotent Mantra:
ॐ नमो भगवते वासुदेवाय
(Oum Namo Bhagwate Vasudeway)
is simple.
It says-
'O Lord!
You are Manifested in the form of Oum!
Our utmost reverence is offered to You,
The One who Manifests Himself only out of a Pure Self!'
ॐ (Oum)= the name of the God.
Namo= reverence is offered to.
Bhagwate= the Omnipotent.
Vasudeway= son of Vasudev= the Purified Self.
The all pervasive impurity of the Real Self is an inflated "ego."
Be wary of it and become worth his Divine Love an Generosity.
