The Heart Sutra translated by Master Xuanzang is beautiful and catchy, and has been copied, recited and engraved by many people. Therefore, it contains great wisdom and has become a textbook for Buddhist practice in past dynasties. These short 260 words not only express the core of Mahayana Buddhism wisdom, but also contain diligent practice, and are known as "classics among classics" and "king of curses".
There are many stories in Buddhist classics about copying and reciting the Heart Sutra to get good results and increase happiness. Emperors, generals, eminent monks, great virtues, calligraphers and writers all advocated writing classics, among which the Heart Classic was the most widely written.
