5.11.17

bhrātṛvyam enaṃ tad adabhra-vīryam upekṣayādhyedhitam apramattaḥ /
guror hareś caraṇopāsanāstro jahi vyalīkaṃ svayam ātma-moṣam //

17. Therefore, arming thyself with devotion to the feet of Hari who is no other than the preceptor and being ever cautious, put an end to this enemy of enormous strength, who has grown very strong through neglect and who, though unreal in himself, is still capable of deluding Atman.
