ajeyaḥ sarvadevānāṃ tvatprasādādahaṃ vibho ..
yathā bhavāmi saṃgrāme tvāṃ vihāya tathā kuru .. 6.70.30
na taṃ svayaṃ mahādevaḥ svaśiṣyaṃ sūdayiṣyati ..
viṣavṛkṣamapi sthāpya kaśchinatti punaḥ svayam .. 31 ..

‘O lord, by your favor, act in such a way that in battle / I may be unconquerable by all the gods, leaving you aside.’ // 30
Mahādeva himself will not destroy his own disciple; / for having planted even a poisonous tree, who cuts it down himself? // 31
