There is nothing in existence that has any purpose, neither does existence itself have any purpose. But the imagined identity is so lost and desperate for security that it will hold up almost any flag in reach and proclaim it has found a purpose. But all ideas from birth to death that are given so much importance have no real substance, they will all collapse. There is nothing to attain in addition to what you already are. Existence is self-sufficient onto itself, you only have to let go of that which is limited and imagined.
