Būr is a transliteration of Sanskrit, or translated as "Polo" and "Polo", whose full name is "Prajna Paramita" (Sanskrit: Praj? āpāramitā) or "Prajna paramita". Free translation of "wisdom"
Prajna, Buddhism refers to the wisdom of knowing everything truthfully, and transliteration is used to express wisdom different from general wisdom.
Mahayana Buddhism calls it "the mother of all buddhas". Prajnaparamita wisdom is not ordinary wisdom, but refers to the wisdom that can realize Tao, realize Tao, practice the certificate, get rid of life and death, and be extraordinary and holy. This is not general wisdom, it belongs to the fundamental wisdom of the Tao. The so-called fundamental wisdom is to transcend common wisdom and common wisdom and understand the origin and essence of metaphysical life. This is not achieved by thinking, but by the wisdom of the whole body and mind. This wisdom is Prajna Paramita. Therefore, the word "wisdom" cannot represent the full meaning of Prajna. Among all the Buddhist scriptures and the works of later bodhisattvas, monks and great virtues, the Diamond Sutra belongs to the Prajna Department in academic classification, so it is called the Prajna Paramita Sutra.
