This separate, limited existence is an illusion.
It is a realm of dream where the eternal, truly free spirits descend in and have limited, unique experiences of human lives.
Therefore everything down here is not truly real. These whole lives are just experiences. These experiences help the eternal spirits to grow, to grow more into joy, more into love, to grow ever toward the divine Source.
Therefore let nothing in this dream world affect you. Pull yourself away from this place and realize the true 'you', that ever free, loving, and joyful spirit in its own world — a world of limitlessness, of pure divine brilliance and utter bliss.
All sorrow in this world is just illusion, nothing more. Seek your own true being, and ponder upon the Truth. And you shall find freedom.
