Lord Buddha had a devotee who was also his cousin. He was a brilliant man, and very devoted. In the beginning, Buddha’s or communion was quite small, but in time it became bigger. So, the devotees close to Buddha became more possessive, and his cousin felt that he owned Buddha, but Buddha can’t be owned by anybody. You cannot say you own the ocean. So, because of this there were some misunderstandings and this cousin turned against Buddha.
When someone pushed the boulder at Buddha, what the people did was they reacted, but Buddha asked them not to react and then he smiled, that is an action. When someone is against you, if you show love and compassion and if you turn the other cheek when they hit you on one cheek then they cannot hit you back. That is a bigger weapon!
