Master Li Tao Te Ching Verse 13

One day Master Li gave a talk to a group of townspeople. Afterwards, one man approached him and said "Wonderful talk today!" Master Li said nothing. A second man approached and said "Everything you said was garbage!" Again, Master Li said nothing. A student came up to the master and asked him why he had shown no reaction either way. Master Li said, "If someone says something good or bad about me, must I be shaped into thinking in a similar manner? Would it not be better for me to be concerned with my own opinion rather than the opinion of another?"
