(You should serve the body, sensory organs, the heart and the mind for they are separate from you.)
- Sharirko nidralu, aalsi, pramaadi, nikamma aur bhogi na banne dena, sharir ki seva hain. (To avoid letting the body become lethargic is the service to the body.)
- Indriyon ko saansarik bhogo main na lagne dena, indriyon ki seva hain. (To avoid letting the sensory organs become craving for worldly pleasures is the service to the sensory organs.)
- Mann ko kissika ahit sochne main, vishayon ke chintan main aur vyarth chintan main na lagne dena, mann ki seva hain. (To avoid letting the heart - think ill for others, think about worldly pleasures and take wasteful tensions - is the service to the heart.)
- Buddhi ko doosro ke kartavya par vichaar na karne dena, doosra kya karta hain, kya nahin - yeh na sochne dena, buddhi ki seva hain. (To avoid letting the mind think - about the responsibilities of others, about what others do and don't - is the service to the mind.)
(Actually speaking, to not get attached / fond of the body, sensory organs, the heart and the mind is the greatest service to them.)
