By worship of the Lord, who is the source of all beings and who is all-pervading, man can, in the performance of his own duty, attain perfection. Chapter 18, Verse 47. It is better to engage in one's own occupation, even though one may perform it imperfectly, than to accept another's occupation and perform it perfectly. Prescribed duties, according to one's nature, are never affected by sinful reactions. Chapter 18, Verse 48.
Every endeavor is covered by some sort of fault, just as fire is covered by smoke.
Therefore one should not give up the work which is born of his nature, O son of Kunti, even if such work is full of fault. Chapter 18, Verse 49. One can obtain the results of renunciation simply by self-control and by becoming unattached to material things and disregarding material enjoyments. That is the highest perfectional stage of renunciation. Chapter 18, Verse 50.
