Bhagavad Gita: Verse 5.7
योगयुक्तो विशुद्धात्मा विजितात्मा जितेन्द्रियः ।
सर्वभूतात्मभूतात्मा कुर्वन्नपि न लिप्यते ॥ ५-७॥
yogayukto viśuddhātmā vijitātmā jitendriyaḥ
sarvabhūtātmabhūtātmā kurvannapi na lipyate
He who is devoted to the Path-of-action, whose mind is quite pure, who has conquered the self, who has subdued his senses, who realises his Self as the Self in all beings, though acting, is not tainted.
