If you realize that all things change, there is nothing you will try to hold on to. If you aren't afraid of dying, there is nothing you can't achieve. Trying to control the future is like trying to take the master carpenter's place. When you handle the master carpenter's tools, chances are that you'll cut your hand.
Seal 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.
To know people is wisdom, but to know yourself is enlightenment. to master people takes force, but to master yourself takes strength. to know contentment is wealth, and to live with strength resolve. to never leave whatever you are is to abide, and to die without getting lost- that is to live on and on.
The transformation toward eternal life is gradual. The heavy gross energy of body, mind, and spirit must first be purified and uplifted. When the energy ascends... then self mastery can be sought.
Those who have compassion when they do battle will be victorious. Those who likewise defend themselves will be safe. Heaven will rescue and protect them with compassion.
