Bill Porter, Road to Heaven (1993):

One of the mountains we visited was Tailaoshan just inside the northwest tip of Fukien Province. A Buddhist layman we met on the trail led us to a cave where an eighty-five-year-old monk had been living for the past fifty years. In the course of our conversation, the monk asked me who this Chairman Mao was whom I kept mentioning. He said he had moved into the cave in 1939 after the spirits of the mountain appeared to him in a dream and asked him to become the mountain’s protector. He hadn’t been down the mountain since then. Disciples and local villagers brought him the few things he needed. And he didn’t need much: flour, cooking oil, salt, and once every five years or so a new blanket or set of robes. His practice was the name of the Buddha: Amitabha, Buddha of the Infinite.
