actually eventhough they were a great teachers for all humanity even if that we don't follow their steeps but they remined the greatest in the world for me ghadi was one of the most great teachers in the world because he adopted a really simple method to humans to love eachother live peacfully wiht eachother even if someone harm you do not do the same try to forgive him and we still can remamber his reaction to the british conquire of india and how he advice his people to avoide violance and new way for asking rights in his appeal to america, in addition to buddha who is a really an idol in the life of so many people, what i'm trying to say is that we failed not they, buddha adopted a simple fylosophy but we didn't follow them. thank you friend
