善者不辯，辯者不善。
Those who are skilled (in the Dao) do not dispute (about it); the disputatious are not skilled in it.
知者不博，博者不知。
Those who know (the Dao) are not extensively learned; the extensively learned do not know it.
聖人不積，既以為人己愈有，既以與人己愈多。
The sage does not accumulate (for himself).
The more that he expends for others, the more does he possess of his own; the more that he gives to others, the more does he have himself.
天之道，利而不害；聖人之道，為而不爭。
With all the sharpness of the Way of Heaven, it injures not; with all the doing in the way of the sage he does not strive.
