No one has ever achieved the results he desired from material activities. On the contrary, everyone has been frustrated again and again. Therefore one must not waste his time in such material activities for sensual pleasure, either in this life or in the next. So many nationalists, economists and other ambitious persons have tried for happiness, individually or collectively, but history proves that they have all been frustrated.
Everyone begins his activities with some plan and ambition, but actually, from the beginning of one's plan to the end, one does not derive any happiness. On the contrary, as soon as one begins acting according to his plan, his life of distress immediately begins. Therefore, one should not be ambitious to dissipate the unhappy conditions of life, for one cannot do anything about them. Ahankara-vimudhatma kartaham iti manyate [Bg. 3.27]. Although one is acting according to false ambitions, he thinks he can improve his material conditions by his activities. The Vedas enjoin that one should not try to increase happiness or decrease distress, for this is futile. Tasyaiva hetoh prayateta kovidah. One should work for self-realization, not for economic development, which is impossible to improve. Without endeavor, one can get the amount of happiness and distress for which he is destined, and one cannot change this. Therefore, it is better to use one's time for advancement in the spiritual life of Krsna consciousness. One should not waste his valuable life as a human being. It is better to utilize this life for developing Krsna consciousness, without ambitions for so-called happiness.
