Bhagavad Gita 5.7
He who is spiritual, pure, has overcome his senses and his personal self, and has realized his highest Self as the Self of all—even though he acts, he is not bound by his actions.
योगयुक्तो विशुद्धात्मा विजितात्मा जितेन्द्रियः।
सर्वभूतात्मभूतात्मा कुर्वन्नपि न लिप्यते॥yogayukto viśuddhātmā vijitātmā jitendriyaḥ|
sarvabhūtātmabhūtātmā kurvannapi na lipyate||
