The video talks about the sacrificing life by Dr. K K Aggarwal, Padma Shri Awardee, Editor-in-chief, IJCP Publications. He will explain the philosophy behind the ‘bali’ which means sacrificing life. Animals are generally sacrificed for certain desires. In olden days, which ever animal you sacrifice that property of that animal is within you. There is upper brain and lower brain, the lower brain has animal kind behavior and we need to sacrifice that. It shouldn’t be actually sacrificing some animal.
