Gangadhara Gowri Mahesha
Sing the glory of Lord Shiva, the consort of Gowri and the one who bears the Ganges and the moon on His head. He illuminates us by destroying the demon "Tripura" who symbolizes the darkness within us. He is the ultimate Lord who drank the deadly poison of "Haalaa-hala" for the welfare of the world during the churning of the ocean. He is verily our Lord Sai Mahesha.
This song is also sung in raga Mayamalavagowla / Bhairav as demostrated in the tutorial.
