अधोमार्गस्थितं कञ्चित् वैष्णवाद्यं तच्छास्त्रकुलात् गुरूकृत्यापि त्यजेत्
Transliteration (IAST)
adhomārgasthitaṃ kañcit vaiṣṇavādyaṃ tacchāstrakulāt gurūkṛtyāpi tyajet
Someone stationed on a lower path — a Vaiṣṇava or the like, belonging to the family of that scripture — he should forsake, even though he had once made him his guru.
