Every one of us, anyone who is engaged in karma . . . Karma means pāpa, sinful activities. And karma means one who is working for his own benefit. He is karmī. The whole world is working so hard not for others' benefit but his personal benefit. That is called karma. Try to understand what is karma. Karma means anyone who is working very hard day and night for his own benefit. That is called karma. And whenever you perform karma for your personal interest there must be some sinful activity. Therefore every karmī is a sinful man. It is clear understanding. No karmī can be without being sinful. Every karmī is. Therefore how to work?
Just like government gives you license, say for . . . one is . . . every businessman is given some license. The municipality gives license. The sales tax department gives license, certificate. There are so many licenses a businessman has to follow—income tax licenses. But there are rules and regulations, because all these departments know it very well that any businessman or karmī, he is sure to commit sinful activities. Therefore there are so many regulations just to stop him as far as possible from sinful activities.
Similarly, there are twenty kinds of viṁśati-prakāśa-dharma-śāstra. How one can live faithfully, religiously, the directions are there in twenty kinds of scriptures made by Parāśara, Manu, and many other sages. There are different types. So therefore it is said here that na niṣkṛtair uditair brahma-vādibhiḥ. Brahma-vādibhiḥ. Brahma-vādī means those who are trying to lead persons to realize Brahman.
The whole direction of the Vedic injunction is to understand that "I am not this material body; I am spirit soul." And in order to understand this factual position, there are so many directions in the dharma-śāstra, or religious scriptures. And you'll find here the Yamadūta or Yamarāja will speak, dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19).
Really, originally, the, I mean to say, regulator of religious principles is the Supreme Personality of Godhead. Therefore Kṛṣṇa is sometimes addressed as dharma-setu. Setu means bridge. We have to cross over. The whole plan is that we have to cross over the ocean of nescience in which we are now fallen. The material existence means it is ocean of ignorance and nescience, and one has to cross over it. Then he gets his real life.
