The One who destroys the Mahishi within
The One who ends duality within her Sadhak
The One who presents the Sakthi to the Sadhaka to face and rid of all dualities, that plague higher realisation.
The One whose Khadga cleaves through all facets that impair quest for the righteous truth, stopping the Sadhak from going In circles.
Hence the name, MAHISHASURASAMHARTRI
