A wise man named Confucius of China is said to have thought over what he intended to say nine times before he uttered a word. It is also said that Tan, the Duke of Chou, interrupted washing his hair, or having a meal, three times in order to see visitors without keeping them waiting. How much more you who have faith in Buddhism should take these examples to heart! Otherwise you will regret it later. Please do not bear a grudge against me. This is the teaching of the Buddha. The essence of Buddhism is the Lotus Sūtra, and the gist of practicing the Lotus Sūtra is shown in the “Never-Despising Bodhisattva” chapter. Contemplate why the Never-Despising Bodhisattva stood on the street to bow to passersby. The true purpose of Śākyamuni Buddha appearing in this world was to teach us how to behave ourselves on a daily basis. Consider this well. The wise are called human beings while the foolish are beasts.
