To manage your mind, know that there is nothing, and then relinquish all attachment to nothingness.
LaoziThe Tao doesn't take sides; it gives birth to both good and evil. The Master doesn't take sides; she welcomes both saints and sinners. The Tao is like a bellows: it is empty yet infinitely capable. The more you use it, the more it produces; the more you talk of it, the less you understand. Hold on to the center.
LaoziSeal the openings, shut the doors, and until your last day you will not be exhausted. Widen the openings, interfere, and until your last day you will not be safe.
