Bhagavad Gita 18.49
असक्तबुद्धिः सर्वत्र जितात्मा विगतस्पृहः । नैष्कर्म्यसिद्धिं परमां संन्यासेनाधिगच्छति ॥
asakta-buddhiḥ sarvatra jitātmā vigata-spṛhaḥ | naiṣkarmya-siddhiṃ paramāṃ sannyāsenādhigacchati ||
Translation
He whose understanding is unattached everywhere, who has subdued himself, from whom desire has departed, reaches by renunciation the supreme perfection of freedom from action.
Reflection
Which of unattached intellect, mastered self, or absence of longing is currently weakest in you?
Read this verse in its chapter: Chapter Eighteen
The bridge from sva-karma to naishkarmya. Three interior conditions are listed. Asakta-buddhi sarvatra, the intellect not clinging anywhere, applied universally, not just in one favored arena. Jita-atma, the self that has been mastered, the lower drives no longer running the operation. Vigata-spriha, the chronic ache of want, departed. These three together produce naishkarmya-siddhi parama, the supreme accomplishment of actionlessness. Naishkarmya here does not mean cessation of action. It means action that no longer accumulates karmic residue, because the inward conditions for residue have been removed. Sannyasena, by this inward renunciation, the state is reached. Outer activity may continue exactly as before.
