There is a certain pattern of behavior prescribed for those actually trying to become perfect. In our Krsna consciousness movement we advise our students not to eat meat, not to gamble, not to engage in illicit sex and not to indulge in intoxication. People who indulge in these activities can never become perfect; therefore these regulative principles are for those interested in becoming perfect and going back to Godhead. Kutinati, or diplomatic behavior, cannot satisfy the atma, the soul. It cannot even satisfy the body or the mind. The culprit mind is always suspicious; therefore our dealings should always be straightforward and approved by Vedic authorities. If we treat people diplomatically or duplicitously, our spiritual advancement is obstructed. Jiva-himsana refers to the killing of animals or to envy of other living entities. The killing of poor animals is undoubtedly due to envy of those animals. The human form is meant for the understanding of Krsna consciousness (athato brahma-jijnasa), for inquiring about the Supreme Brahman. In the human form, everyone has a chance to understand the Supreme Brahman. The so-called leaders of human society do not know the real aim of human life and are therefore busy with economic development. This is misleading. Every state and every society is busy trying to improve the quality of eating, sleeping, mating and defending. This human form of life is meant for more than these four animal principles. Eating, sleeping, mating and defending are problems found in the animal kingdom, and the animals have solved their problems without difficulty. Why should human society be so busy trying to solve these problems? The difficulty is that people are not educated to understand this simple philosophy. They think that advancement of civilization means increasing sense gratification.
