"The Supreme represented as the ocean has overflown to the whole creation. He has created at first creatures according to the deserts of their various past deeds.
He is the ruler of the universe and the munificent giver of gifts to the devotees.
He dwells together with Uma (His SHAKTI Granting spiritual illumination) in the hearts of devotees which are holier than other parts of their body (the seat of the Divine) and therefore superior and elevated like a peak and affording protection.
The liva who is his abode grows to be infinite. He is the Lord who delights the individual souls by guiding according to their deeds and conferring on them fruits of their actions".
