The adept traveler leaves no tracks, the adept speaker reveals no opportunity for reproach, the adept accountant needs no calculator.
The skilled locksmith opens doors that are locked to others, the experienced sailor ties knots that others cannot untie.
The wise person is excellent at helping others, and does not reject any of them. Indeed, the wise person is excellent at taking care of all things, and therefore does not reject the physical world. This is called practicing enlightenment.
The good person is the bad person’s teacher, and the bad person is the good person’s lesson. To honor the teacher you must also cherish the lesson. Even though this wisdom may seem perplexing, it is one of the Tao’s crucial mysteries.
(from Tao Te Ching, verse 27, translation by Robert Brookes)
