If one does not accept the authority of the Supreme Godhead in matters of religion and morality, one must explain why two persons of the same moral standard achieve different results
SB Canto 4
A person who is always subjected to the rules and regulations of repeated birth and death cannot accommodate anything beyond materialistic ideas. Since King Vena was such a man, he did not believe in the existence of God. Modern civilization agrees with the principles of King Vena, but factually if we scrutinizingly study all the conditions of religion, economic development, sense gratification and liberation, we must accept the principles of the authority of the Supreme Personality of Godhead. According to Vedic literature, religion consists only of the codes of law given by God.
If one does not accept the authority of the Supreme Godhead in matters of religion and morality, one must explain why two persons of the same moral standard achieve different results. It is generally found that even if two men have the same moral standards of ethics, honesty and morality, their positions are still not the same. Similarly, in economic development it is seen that if two men work very hard day and night, still the results are not the same. One person may enjoy great opulence without even working, whereas another person, although working very hard, does not even get two sufficient meals a day. Similarly, in the matter of sense gratification, sometimes one who has sufficient food is still not happy in his family affairs or sometimes is not even married, whereas another person, even though not economically well off, has the greatest opportunity for sense gratification. Even an animal like a hog or a dog may have greater opportunities for sense gratification than a human being. Aside from liberation, even if we consider only the preliminary necessities of life—dharma, artha and kāma (religion, economic development and sense gratification)—we will see that they are not the same for everyone. Therefore it must be accepted that there is someone who determines the different standards. In conclusion, not only for liberation must one depend on the Lord, but even for ordinary necessities in this material world. Pṛthu Mahārāja therefore indicated that in spite of having rich parents, children are sometimes not happy. Similarly, in spite of valuable medicine administered by a competent physician, sometimes a patient dies; or in spite of having a big safe boat, sometimes a man drowns. We may thus struggle to counteract impediments offered by material nature, but our attempts cannot be successful unless we are favored by the Supreme Personality of Godhead.
