The One who is the waves on the river
She who is the pranic flow of the rivers.
Here the river is also the Nadis in the human body, she whose grace allows for greater flow of Prana within a body.
The realisation needs to be had, that she who is the maker of the cosmos, the mother of Brahma Deva, who creates the universe. It is her grace that can accelerate a Jiva in the path to enlightenment by higher flow of Prana.
Hence the name, Tarangini
