Tea & Buddhism
Buddhism was founded in 535 B.C. by Siddhartha Gautama (563-483 B.C.) in Lumbini of Northern India (now currently inside Nepal. Buddhism's Mahayana tradition entered into China as a foreign religion during Han Dynasty (206 B.C. - 220 A.D.) by trying to explain the essence of human life.
In the Buddhist temple, monks are very strict about their diet: where vegetables, rice and wheat products are the sole resource for their daily nutrition. Tea on the other hand as an exception, tea in essence is a vegetable so drinking tea breaks no- monastery rules.
Additionally, drinking tea can help monks meditate by keeping them awake. Tea's bitter taste can refer to Buddhist suffering; the clean and clear tea liquid can refer to the monastery rule of self-discipline, and calm.
