Explanation
Krishna uses the image of fire again. Knowledge is not mild information; it is transformative fire. It burns ignorance, egoic intention, and karmic bondage.
Read the traditional commentary
Krishna offers a vivid and memorable simile for the transformative power of wisdom. Just as a blazing fire (samiddho'gniḥ) turns a heap of firewood entirely to ash, so the fire of knowledge (jñāna-agni) consumes the binding force of all one's actions. The accumulated karma that would otherwise tie us to repeated birth is, as it were, incinerated by realization.
The metaphor is precise. Fire does not remove the wood by carrying it away; it transforms its very nature into ash that can bind nothing. Likewise, knowledge does not necessarily stop us from acting, but it burns away the egoic ignorance that makes action binding.
Once 'I am the doer, I crave the fruit' is reduced to ashes, deeds lose their grip on the soul. This single image captures why the Gita esteems knowledge so highly: it is the purifying flame that frees.
