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.
LaoziWithout going out-of-doors, one can know all he needs to know. Without even looking out of his window, one can grasp the nature of everything. Without going beyond his own nature, one can achieve ultimate wisdom. Therefore, the intelligent man knows all he needs to know without going away, And sees all he needs to see without looking elsewhere, And does all he needs to do wihout undue exertion.
Laozi
