Bhagavatapurana 5.5.15

5.5.15

putrāṃś ca śiṣyāṃś ca nṛpo gurur vā mal-loka-kāmo mad-anugrahārthaḥ /
itthaṃ vimanyur anuśiṣyād ataj-jñān na yojayet karmasu karma-mūḍhān /
kaṃ yojayan manujo 'rthaṃ labheta nipātayan naṣṭa-dṛśaṃ hi garte //

15. The King or the Preceptor who would attain to My world or My grace should get free from passions and direct thus his sons or pupils. He ought not to put into the ways of Karma them who are ignorant of Truth and who are already bewildered in the path of Karma; what purpose would a man, like one who pushes the blind into a pit, gain by directing those people into the path of karma?
