All religious masters like Christ, Mohammed, Buddha, Krishna etc lived their life for spreading truth. It is only blinded people who made them political and completely forgot the message they taught us. Life is a chain of birth and death Life is understood as a chain of birth and death. The whole life is dictated by thoughts. Throughout the life we are occupied by only thoughts.
Life just becomes a continuous flow of thoughts.
Desires arise in us as thoughts. We are born out of desire. We live to fulfill that desire. Some desire to enjoy the senses repeatedly life after death while others desire to get free from this ever ending chain of life and death. This chain is broken only through proper understanding.
