Bhagavad Gita 13.32
The Supreme Spirit, O Prince, is without beginning, has no qualities, and is imperishable. Though it is within the body, it does not act, nor is it affected by action.
अनादित्वान्निर्गुणत्वात्परमात्मायमव्ययः।शरीरस्थोऽपि कौन्तेय न करोति न लिप्यते॥anāditvānnirguṇatvātparamātmāyamavyayaḥ|śarīrastho'pi kaunteya na karoti na lipyate||
