Under the guidance of the brahmanas in the varnasrama society, anyone performing work according to that can attain all perfection, by engaging his proclivity in the service of Krishna: sva karmana tam abhyarca siddhim vindati manavah. By worshiping the Supreme Lord by performance of their work, then everyone can achieve perfection.

Everyone is intoxicated with the prospect that we are going to produce goods, and have more factories, and everyone’s standard of living will improve, and India will become a great superpower, and we’ll have lots of sense gratification. But this is karma bandhana, entanglement in material activities. They don’t see that by doing so they are bringing in all the problems that the Western world has already generated along with economic development.

When we are divorced from spiritual cultivation, from understanding that the purpose of life is God realization and not sense gratification, then we will think, “Why shouldn’t we do whatever we like as long as it doesn’t harm others?” But they don’t know that we are harming ourselves by such a mentality, because: na te viduh svartha-gatim hi visnum, our real self interest is to understand Krishna; and any activity performed without this in mind is apasvartha, or that which is not actually in our self interest.
