Although the body is temporary, it always gives one trouble in many ways, but human civilization is now unfortunately based on tanu-mani, the bodily concept of life, by which one thinks, I belong to this nation, I belong to this group, I belong to that group, and so on. Each of us has his own ideas, and we are becoming increasingly involved, individually, socially, communally and nationally, in the complexities of karmanubandha, sinful activities. For the maintenance of the body, men are killing so many other bodies and becoming implicated in karmanubandha. Therefore Srila Jiva Gosvami says that tanu-mani, those in the bodily concept of life, are papi, sinful persons. For such sinful persons, the ultimate destination is the darkest region of hellish life (ganta tamo ndham). In particular, a person who wants to maintain his body by killing animals is most sinful and cannot understand the value of spiritual life. In Bhagavad-gita (16.1920) the Lord says:

Those who are envious and mischievous, who are the lowest among men, are cast by Me into the ocean of material existence, into various demoniac species of life. Attaining repeated birth among the species of demoniac life, such persons can never approach Me. Gradually they sink down to the most abominable type of existence. A human being is meant to understand the value of human life, which is a boon obtained after many, many births. Therefore one must free oneself from tanu-mani, the bodily concept of life, and realize the Supreme Personality of Godhead.
