To be nonviolent to human beings and to be a killer or enemy of the poor animals is Satan's philosophy. In this age there is always enmity against poor animals, and therefore the poor creatures are always anxious. The reaction of the poor animals is being forced on human society, and therefore there is always strain of cold or hot war between men, individually, collectively or nationally.
A. C. Bhaktivedanta Swami PrabhupadaThe artist draws a picture of a rose very nicely with all attention and artistic sense, and yet it does not become as perfect as the real rose. If that is the real fact, how can we say that the real rose has taken its shape without Intelligence behind the beauty?
A. C. Bhaktivedanta Swami PrabhupadaTherefore a person fully absorbed in the bodily concept of life is surely killing himself by not making spiritual progress. Such a person is called pasu-ghna. Especially excluded from spiritual life are the animal hunters, who are not interested in hearing and chanting the holy name of the Lord. Such hunters are always unhappy, both in this life and in the next. It is therefore said that a hunter should neither die nor live because for such persons both living and dying are troublesome.
