गुरुभक्त्या च धृत्या च धर्मभक्त्या श्रुतेन च ।विष्णुभक्त्या च सततं ज्ञानमुत्पद्यतेऽमलम् ॥
In plain words
Devotion to the teacher. Steadiness that holds. Devotion to dharma. What you have heard from śruti. Devotion to Viṣṇu — and all of it kept up without a break. Out of these, knowledge arises, and it arises without a stain.
Close to the Sanskrit
By devotion to the guru, and by steadfastness, and by devotion to dharma, and by what has been heard, and by devotion to Viṣṇu — constantly — stainless knowledge arises.
