Quotes from Zen Master Dogen

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.

Those who regard worldly affairs as a hindrance to buddha dharma think only that there is no buddha dharma in the secular world; they do not understand that there is no secular world in buddha dharma.

If you cannot find the truth right where you are, where else do you expect to find it?
