子曰:“学而时习之,不亦说乎?有朋自远方来,不亦乐乎?人不知而不愠,不亦君子乎?”
The Master said, “Is it not pleasant to learn with a constant perseverance and application?”
“Is it not delightful to have friends coming from distant quarters?”
“Is he not a man of complete virtue, who feels no discomposure though men may take no note of him?”
