reason behind bali in hindhu - why god created kone animal killing another for food.

 Do only gods like bhog; do goddesses not like it?

For devis, traditionally, there would be blood sacrifices – goats, buffaloes, birds. These days it is not popular because of animal rights. A devi is Raktavilasini, one who loves rakt, blood.

We can take it literally, but there is a metaphorical aspect to it. Bhudevi, the earth goddess, is considered to be a cow whose milk sustains everyone. But how will she sustain herself? In the form of Gauri, she gives milk, and in the form of Kali, she drinks blood – the cycle of life, as it were. This is to emphasise the idea that whenever you eat, you’ve killed something, sacrificed someone, offered bali.

Plant food comes from farms which were created after decimating forests, destroying mountains and rivers, killing countless creatures in the process. The Devi always reminds you that to build your civilisation, sanskriti, you destroy prakriti, nature. And so she demands blood, even narabali, human sacrifice.
