The best knowledge to gain is to understand your own pain in such a deep way that any being’s pain will be understood easily. Don’t hurt any being any animal mercilessly cause the pain will come back to us and then no one will be able to help us. The way in China they kill dogs it is really very very painful please don’t do this to any animal they can’t speak but they feel the pain just like us , rather more then us as they can’t speak. Help all and let all live and everyday we all should work on our own self to make ourselves calm beings. We are not on this planet to give pain we are here to erase pain.
