duhkham ity eva yat karma
sa kritva rajasam tyagam
naiva tyaga-phalam labhet
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.
Commentary by Srila Prabhupada
One who is in Krishna consciousness should not give up earning money out of fear that he is performing fruitive activities. If by working one can engage his money in Krishna consciousness, or if by rising early in the morning one can advance his transcendental Krishna consciousness, one should not desist out of fear or because such activities are considered troublesome. Such renunciation is in the mode of passion. The result of passionate work is always miserable. If a person renounces work in that spirit, he never gets the result of renunciation.
Commentary by Sri Visvanatha Cakravarti Thakur
Even though one knows that performance of nitya karma is necessary and to do it is praiseworthy and to neglect to do it is a sinful, if one rejects the action thinking it is useless trouble to the body, it is rajasa tyaga. One will not attain the desired result of tyaga, knowledge, by doing so.
