7.2.8

macchūlabhinnagrīvasya bhūriṇā rudhireṇa vai /
asṛkpriyaṃ tarpayiṣye bhrātaraṃ me gatavyathaḥ //

7. & 8. "With the profuse blood of that Hari who changed His nature, (though pure light) and became a wild animal (Boar) through His Maya and who helps any one that waits on Him, [fickle-minded like a boy] and who will have His head cut off by my trident, I shall gratify my brother thirsting for blood and be rid of the pain at my heart.
