One who uses this body the way cats and dogs do for sense grantification is a miser. He does not know how to use his "million dollars."
Indulgence in animal killing for the taste of the tongue is the grossest kind of ignorance.
Prabhupada is showing us the way to return to the spiritual world. We just have to follow His instructions. Then we will reach our destination.
Milk is very good and nourishing, but when it is touched by the mouth of a snake it is no longer nourinshing; rather, it becomes a source of death. Similarly those who are not strictly in the Vaisnava discipline should not make a business of Srimad Bhagavatam and become a cause of spiritual death for so many heares.
