Sanskrit

परशिष्ये खले क्रूरे अभक्ते गुरुपादयोः।
निर्विकल्पमतीनां तु वीराणाम् उन्नतात्मनाम्॥ १५८॥

Transliteration

paraśiṣye khale krūre abhakte gurupādayoḥ |
nirvikalpamatīnāṁ tu vīrāṇām unnatātmanām || 158 ||

Translation

These teachings should not be disclosed to other disciples, to those who are evil and cruel, or to those who have not surrendered to the feet of the guru. (They should only be revealed) to advanced souls, who are self-controlled and whose minds are free of vikalpas.
