The "bitterness" of Buddha is the first, and the "bitterness" of tea is the foundation; The relationship between Buddha and tea is based on the heart, that is, the epiphany and feeling of the soul. So "tea Buddha makes sense." Jiashan Temple is a famous Buddhist shrine and the ancestral hall of tea Zen. "Jiashan Temple Zen Tea Art" allows tea drinkers to practice Buddhism, understand the tea ceremony, participate in the "bitter truth" and appreciate the real "tea Zen blindly". Note: Jiashan Temple in Shimen County, Changde is called Tea Zen Temple in ancient and modern times. In Jiashan's history, there once appeared a figure famous for the good quality of Biyan Spring, that is, Yuan Wu Keqin, a monk in the Song Dynasty. Master Wu Yuan, then the abbot of Jiashan Temple, devoted himself to studying the relationship between Zen and tea, savored the mystery of tea with the idea of Zen and speculation, and finally realized that he had written the words "Zen tea blindly". "Tea Zen blindly" can be regarded as an important feature of China tea culture, which is not only an incisive summary of the internal principles of tea Zen, but also refers to the consistency of tea drinking and meditation methods. Tea drinking is a "thrifty" realm and a symbol of Buddhism's "freedom". Tea can make monks enter the ideal Zen realm, and the Zen realm is also in line with the mind of tea people. It is at this height that tea Zen can be regarded as "blindly", that is, the profound connotation of "blindly tea Zen"

The original "Tea Zen Blindly" written by Zen master Wu Yuan was brought to Japan by disciples and is now in the Daejeon Temple in Nara, Japan. As the treasure of the town temple, it is the highest purpose and sacred thing of Japanese tea ceremony.
