Bhagavad Gita · Chapter 13: The Field and the Knower of the Field

Bhagavad Gita 13.28

samaṃ paśyanhi sarvatra samavasthitamīśvaram | na hinastyātmanātmānaṃ tato yāti parāṃ gatim ||

Seeing the same Lord dwelling equally everywhere, a person does not harm the self by the self, and so reaches the highest goal.

Modern context

Seeing the same Lord everywhere, a person 'does not harm the self by the self'. This can be read two ways, and both are true. If the same self is in everyone, harming another is harming oneself. And a person who sees clearly stops sabotaging their own life through ignorance and bad choices. Both kinds of harm end when the truth is seen.
