Introduction to the mountain gate: Walking towards Zhongtai Zen Temple, you are facing three gates, which are wider in the middle and slightly narrower on both sides, but they are also extremely open and three stories high. It is said that the three mountain gates are 12 meters high and weigh 5 tons, but they are easy to push. There is a pair of couplets on both sides of the mountain gate: In the middle stage, all living beings are holding flowers and smiling and lighting up to pass down the ancestral will. In the west, learning from the scriptures and the teachings of the great sages, evolution is everywhere; through the first pass, the second pass, the second pass and the third pass of life and death, you can see your true face. Six roots, six dusts, and six consciousnesses, a total of eighteen netherworlds, are the realization of the three bodies of the Tathagata.
