One is acting in auspicity, and one is acting viparītāni, just the opposite, inauspicity. In this way we are becoming entangled, life after life. Karinam guṇa-sango 'sti.
In other place it is said, karmaṇā daiva-netreṇa (SB 3.31.1): "As we are acting auspicious or inauspicious, by higher supervision, higher consideration, judgment, we are getting different body." Otherwise why there are so many varieties of body? This is the cause. One is getting auspicious body, one is getting inauspicious body, but there is one opportunity that. . . If you want to change materially your auspicious or inauspicious position, that cannot be done. It is fixed up. It cannot be done otherwise. Suppose a man has got a nice body; a dog has got inferior body. You cannot change the. . . Bodily, you cannot make a man dog or a dog man. That is not possible. But spiritually you can do. Spiritually, a bad man or bad dog even can be elevated to the highest perfection.
Therefore the conclusion is if you act spiritually, then it is bhadrāṇi, or auspicious. If you act materially, on the bodily concept of life, that is inauspicious. This is the conclusion. And that is being watched by the authorities, as we have already explained, the witnesses. God is the original chastiser or awarder, but there are so many witnesses—that we have already discussed—sūryaḥ agniḥ khaṁ marud devaḥ somaḥ. Everywhere it is thoroughly watched. So we must be very careful, that we have got this human form of body—how to act? The act means first of all you know what is your position. That is the first instruction in the Bhagavad-gītā, that "Your position is that you are not this body. Your position is that you are the proprietor of the body; you are spirit soul."
