How to read this

How to chant: each line is one pāda (quarter-verse); chant it in one breath. The hyphen (-) divides the syllables, inside a word and across a sandhi join, so every pāda shows its 8 syllables (11 in triṣṭubh verses). A consonant cluster is divided after its first consonant (kar-ma, vet-ti): that syllable is held longer. Mark above a syllable: guru, long (two beats); laghu, short (one beat). | closes the half-verse, || the verse; the number is the syllable count of the pāda.

Deeper Explanation – Chapter 4 Verse 37

Context

Krishna continues his praise of knowledge with the image of fire (following 4.36).

Meaning

The accumulated karma of countless actions is like a great pile of firewood. Knowledge of the Self is like a blazing fire that consumes it all. Once burned, the wood cannot produce flames again. The karmic seeds lose their power to produce future bondage.

This image complements the boat of the previous verse. The boat carries us across; the fire burns away what binds us. Self-knowledge is not merely information; it is a transforming force that changes our relationship with the past.

In Practice

Light a lamp or candle today and reflect on this verse: let the flame remind you of the power of knowledge to burn away what binds you.
