Translation
"The lotus feet of the spiritual master are the only abode of pure devotion; I bow to them with great reverence."
Meaning
A Bengali song by Narottama Dasa Thakura from Prema-bhakti-candrika about the role of the guru: by his mercy one crosses the ocean of material existence and attains Krishna; his words purify the heart, and attachment to his feet is the highest perfection. Srila Prabhupada often sang it; temples sing it at guru-puja.
