Chapter 13 · The Field and the Knower · Krishna said
Bhagavad Gita 13.32 — The Self is untouched
अनादित्वान्निर्गुणत्वात्परमात्मायमव्ययः। शरीरस्थोऽपि कौन्तेय न करोति न लिप्यते ॥
anāditvānnirguṇatvātparamātmāyamavyayaḥ | śarīrastho'pi kaunteya na karoti na lipyate ||
Meaning
Because it has no beginning and is beyond the qualities, this imperishable Supreme Self, though living in the body, Arjuna, neither acts nor is stained.
