Chapter 4 · Knowledge and Renunciation of Action · Krishna said
Bhagavad Gita 4.21 — Simple living, no sin
निराशीर्यतचित्तात्मा त्यक्तसर्वपरिग्रहः। शारीरं केवलं कर्म कुर्वन्नाप्नोति किल्बिषम् ॥
nirāśīryatacittātmā tyaktasarvaparigrahaḥ | śārīraṃ kevalaṃ karma kurvannāpnoti kilbiṣam ||
Meaning
Without longing, with mind and body controlled, giving up all possessiveness, doing only bodily work, such a person incurs no sin.
