"Hammer Blows to Delusion" — a blunt devotional hymn by Shankaracharya that repeatedly interrupts a catalogue of worldly attachments (wealth, sensuality, family, youth) with a single refrain: turn and worship Govinda, because none of it will save you at death.

The foundational text defining devotion (bhakti) itself — its nature, why it is superior to knowledge or ritual alone, and the concrete practices (sadhanas) that develop it, moving from lower to supreme devotion.
