The mystical techniques for achieving immortality are revealed only to those who have dissolved all ties to the gross worldly realm of duality, conflict, and dogma. As long as your shallow worldly ambitions exist, the door will not open.
LaoziDo not imagine that an integral being has the ambition of enlightening the unaware or raising worldly people to the divine realm. To her, there is no self and other, and hence no one to be raised; no heaven and hell, and hence no destination.
Laozi
