11.2.37

bhayaṃ dvitīyābhiniveśataḥ syād īśād apetasya viparyayo 'smṛtiḥ /
tan-māyayāto budha ābhajet taṃ bhaktyaikayeśaṃ guru-devatātmā //

37. He who has turned away from the Supreme Lord, is, under the force of Maya, subject to fear through attachment to a second existence, to misapprehension and loss of memory; therefore

the discerning ought to worship Him with faith and with unmixed devotion to the Guru and the Deity.
