यस्य देवे परा भक्तिर्यथा देवे तथा गुरौ ।तस्यैते कथिता ह्यर्थाः प्रकाशन्ते महात्मनः ॥
In plain words
Whoever holds supreme devotion for God — and holds the teacher exactly as he holds God — for that great soul, these meanings, once spoken, light up.
Close to the Sanskrit
Of whom there is supreme devotion toward God, and as toward God so toward the teacher — for him, that great-souled one, these meanings that have been declared do indeed shine forth.
