yajna-dana-tapah-karma na tyajyam karyam eva tat। yajno danam tapas chaiva pavanani manisinam॥ 18.5 ॥

Sri Krishna said: O Arjuna, Acts of sacrifice, charity and penance are not to be given up; they must be performed. Indeed, sacrifice, charity and penance purify even the great souls.

etany api tu karmani sangam tyaktva phalani cha। kartavyaniti me partha niscitam matam uttamam॥ 18.6 ॥

Sri Krishna said: O Arjuna, All these activities should be performed without attachment or any expectation of result. They should be performed as a matter of duty, That is My final opinion.

niyatasya tu sannyasah karmano nopapadyate। mohat tasya parityagas tamasah parikirtitah॥ 18.7 ॥

Sri Krishna said: O Arjuna, Prescribed duties should never be renounced. If one gives up his prescribed duties because of illusion, such renunciation is said to be in the mode of ignorance.

duhkham ity eva yat karma kaya-klesa-bhayat tyajet। sa kritva rajasam tyagam naiva tyaga-phalam labhet॥ 18.8 ॥

Sri Krishna said: O Arjuna, Anyone who gives up prescribed duties as troublesome or out of fear of bodily discomfort is said to have renounced in the mode of passion. Such action never leads to the elevation of renunciation.
