There is no happiness in the material world.
In the material world we are struggling for existence with the hope that someday in the future we will be happy. Yet we are bewildered. An animal in the desert sees a mirage, a shadow of water, and he runs after this shadow again and again. He runs further and further, and in this way, as he crosses the hot sands, he becomes more and more thirsty and he finally dies. Our struggle for existence is like this. We are thinking, “Let me go a little further. There will be water eventually. There will eventually be happiness.” Yet there is no water in the desert. Those who are unintelligent, who are like animals, seek happiness in the desert of the material world. This false attachment has to be given up by the process of bhakti-yoga. This must be taken up very seriously, not artificially. Krishna in all seriousness wants to see whether one has finished all his material desires. When Krishna sees this, He is very pleased. We are actually busy with dharma, artha, kama, and moksa, but when we transcend these, bhakti begins.
If we study the history of the world, we see that it is simply a history of struggle. Mankind attempts to relieve its miserable condition, but it simply brings about another miserable condition. As we try to overcome one problem, another problem arises. Our determination to renounce our association with this material world is called Mukti. Mukti means coming to the spiritual platform. Since we belong to the spiritual atmosphere, it is impossible for us to be happy in the material atmosphere. If a land animal is placed in water, he will simply struggle for existence, despite being an expert swimmer. We have come into this material world to gratify our senses, but our attempts will never be successful. If we actually want to attain a state beyond fear, we have to accept this bhakti-yoga process enunciated by Lord Kapiladeva.
