Translation

BG 18.45: By fulfilling their duties, born of their innate qualities, human beings can attain perfection. Now hear from me how one can become perfect by discharging one’s prescribed duties.

Commentary

Swa-dharma is the prescribed duties based upon our guṇas and station in life. Performing them ensures that we use the potential abilities of our body and mind in a constructive and beneficial manner. This leads to purification and growth, and is auspicious for the self and society. And since the prescribed duties are in accordance with our innate qualities, we feel comfortable and stable in discharging them. Then, as we enhance our competence, the swa-dharma also changes and we step into the next higher class. In this manner, we keep advancing by dutifully executing our responsibilities.
