If you want to travel the Way of Buddhas and Zen masters, then expect nothing, seek nothing, and grasp nothing.
No matter how bad a state of mind you may get into, if you keep strong and hold out, eventually the floating clouds must vanish and the withering wind must cease.
Do not be concerned with the faults of other persons. Do not see others' faults with a hateful mind. There is an old saying that if you stop seeing others' faults, then naturally seniors and venerated and juniors are revered. Do not imitate others' faults; just cultivate virtue. Buddha prohibited unwholesome actions, but did not tell us to hate those who practice unwholesome actions.
A fool sees himself as another, but a wise man sees others as himself.
