niyatasya tu saMnyaasaH karmaNo nopapadyate ।

mohaattasya parityaagastaamasaH parikiirtitaH ॥१८- ७॥

Translation

Eschew renunciation of prescribed actions.
Their relinquishment out of temptation is proclaimed tamasic.

Translation

Renunciation of obligatory work (or duty) is not proper. The abandonment of duty is due to delusion, and is declared to be Taamasika Tyaaga.

Translation

Prescribed duties should never be renounced. If, by illusion, one gives up his prescribed duties, such renunciation is said to be in the mode of ignorance.
