Dharma, I have explained, occupational duty. So long we have got this material body, we have got particular type of occupational duty. We are preaching to the world not any occupational duty, but we are preaching eternal duty.
This occupational duty is in connection with the body. That is not eternal. Suppose this life I've got a body, human body or Brāhmiṇ body or a son in the Rockefeller family, and according to that body I have got a particular type of duty, standard of living. Deha-yogena dehinām (SB 7.6.3). But as soon as the body's changed—I get another body—the whole duty changed. Now I may have a very comfortable body, American body, Rockefeller family body, but next life, according to my karma, we are preparing our next life.
Suppose if I get the body of a dog, then my occupational duty will be "Gow! Gow!" Because according to the body the duty is changed. So these occupational duties, they are not permanent. But I am eternal, na hanyate hanyamāne śarīre (BG 2.20). By the destruction of this body, I am not destroyed. I remain, I simply enter another body. I, as spirit soul, I remain. Just like I'm entering different bodies in this life. I was a child, I enter another body.
Just like this small child, Sarasvatī. According to the body, she is acting. She's acting sometimes nonsense, but we take it delight, because she is child. But the same nonsense if I do in another body, a grown-up body, that will be ridiculous. In this child body, she is naked, but people enjoy it. But when she is grown up and she is ladylike, she is young girl, if she becomes naked, oh, that is ridiculous. So here in this life also we see according to the change of the body, the duty is changing, the activities are changing.
