“‘I will not engage in the kind of speech that is low, crude, ordinary, ignoble, and pointless. Such speech doesn’t lead to disillusionment, dispassion, cessation, peace, insight, awakening, and extinguishment. Namely: talk about kings, bandits, and chief ministers; talk about armies, threats, and wars; talk about food, drink, clothes, and beds; talk about garlands and fragrances; talk about family, vehicles, villages, towns, cities, and countries; talk about women and heroes; talk at the street market and the place for water pots; talk about the departed; motley talk; tales of land and sea; and talk about being reborn in this or that state of existence.’ ”
