The Buddha was committed to ending suffering. What if suffering is what makes us human? What if suffering is the consequence of imagining the world different than it is? What if my belief that I can make choices that will change my world causes me to suffer because I am a social animal and often take responsibility for things I cannot control?
Is the premise of ending suffering also an illusion? Isn't a belief that is based on Siddhartha's life experience an attachment to his perspective? Does his desire to share this perspective with others lead to his own suffering?
