釋中，初科。六諍本者，不出三毒；上二是瞋，次一即貪，下三並癡。一切諍起，不越此六，故云本也；能治此六，則無諍矣。

In the explanation, the first section: the six roots of dispute do not go beyond the three poisons; the first two are anger, the next one is greed, and the lower three are ignorance. The arising of all disputes does not exceed these six, hence called "roots"; if one can counter these six, then there will be no dispute.
