Cosmic joke is the greatest joke ever told. It usually takes the entire length of your existence to tell but sometimes people can catch a glimpse of it during the psychedelic journey. It is the joke that everybody gets to share when we are released from this experience and return to being part of a single consciousness. We remember then that we are all one , we are everyone, every experience, every thought.
"Nobody lives, nobody dies. Nothingness lives, nothingness dies. You are not. Have a good laugh at this situation. You are not and you exist. You are not and you are. This is the cosmic joke"
