Bhagavad Gita · Chapter 13: The Field and the Knower of the Field
Bhagavad Gita 13.29
प्रकृत्यैव च कर्माणि क्रियमाणानि सर्वशः ।
यः पश्यति तथात्मानमकर्तारं स पश्यति ॥
prakṛtyaiva ca karmāṇi kriyamāṇāni sarvaśaḥ | yaḥ paśyati tathātmānamakartāraṃ sa paśyati ||
One who sees that all actions are done by nature alone, and that the self is not the doer, truly sees.
Modern context
Another form of true seeing: all actions are done by nature, and the self is not the doer. This repeats chapter 3's teaching. The point is not to escape responsibility, but to escape the crushing sense that everything depends on 'me'. Nature acts through body and mind; the self watches. Seeing this, a person can act with full energy and without the weight of ego.
