因時易以為仁,因道易以達人。
One’s empathy must be adjusted to differing circumstances; the assistance one extends to others must be adjusted to the differing principles of those involved.
營利者多患,輕諾者寡信。
One who seeks to multiply his gains will have many who would harm him; one who makes promises lightly will have few willing to believe him.
Literally “up to the present moment.”
