Bhagavad Gita Chapter 5.13
sarva-karmāṇi manasā
sannyasyāste sukhaḿ vaśī
nava-dvāre pure dehī
naiva kurvan na kārayan
Translation
When the embodied living being controls his nature and mentally renounces all actions, he resides happily in the city of nine gates [the material body], neither working nor causing work to be done.
