“Nārada Muni continued, ‘My dear hunter, your business is killing animals. That is a slight offense on your part, but when you consciously give them unnecessary pain by leaving them half-dead, you incur very great sins.’
PURPORT
This is another good instruction to animal killers. There are always animal killers and animal eaters in human society because less civilized people are accustomed to eating meat. In Vedic civilization, meat-eaters are advised to kill an animal for the goddess Kālī or a similar demigod. This is in order not to give the animal unnecessary pain, as slaughterhouses do. In the  balidāna  sacrifice to a demigod, it is recommended to cut the throat of an animal with one slice. This should be done on a dark-moon night, and the painful noises expressed by the animal at the time of being slaughtered are not to be heard by anyone. There are also many other restrictions. Slaughter is only allowed once a month, and the killer of the animal has to suffer similar pains in his next life. At the present moment, so-called civilized men do not sacrifice animals to a deity in a religious or ritualistic way. They openly kill animals daily by the thousands for no purpose other than the satisfaction of the tongue. Because of this the entire world is suffering in so many ways. Politicians are unnecessarily declaring war, and, according to the stringent laws of material nature, massacres are taking place between nations.

No one should think that he has the freedom to kill animals and not suffer the consequences. One cannot be safe by doing this. Nārada Muni herein says that animal
