"The View of the Infinite Life" says: "If you have wisdom, you will get the greatest happiness by pulling out three hardships, hence the name' the general trend'." "Four Yi Jing" said: "I threw my foot in one place and shook it hard, hence the name. "Big is the dharma body, so it is named big because it is poor. The potential is provable, Prajna paramita. Breaking troubles and confusions with prajnaparamita wisdom, hiding demons and complaining outside, hence the name potential. It is the ultimate meaning, that is, getting rid of morality, approaching bodhisattva and approaching Buddha, hence the name. Therefore, the third volume of "Chinese Sadness Sutra" said that Amitabha was destroyed and avalokitesvara was replaced; After the death of Guanyin Bodhisattva, she changed from the general trend to a bodhisattva disguised as a Buddha, mastered the right of transformation and made good use of Baoshan. He "shines all things with wisdom and light, so that he can gain supreme power from the three lands (referring to the three evil tendencies of hell, hungry ghosts and animals)", so he is called the Bodhisattva. The treasure jar on his head contains the light of wisdom, so that the light of wisdom can shine on all sentient beings in the world, freeing them from the disasters of blood, fire and sword and gaining supreme power. According to legend, its Dojo is in Langshan, Nantong, Jiangsu.
