Introduction to Xiantao Xianrui: It is said that Master Zhang came from a poor family when he was young. One day he went into the mountains to collect firewood and met two old men at the top of the mountain. They had childish faces and white hair, wearing Taoist clothes. They were playing chess. There was a half red and half green grain on the chessboard. The peach, Dharma Master crept forward to watch the game, watching the game quietly. The two old men saw that although the Dharma Master was young, he behaved well, so they handed the peach to the Dharma Master to eat. The Dharma Master ate half of the red peach and felt that the green peach was difficult to swallow, so he secretly threw away the remaining peach. The old man waved his hand to signal him to start. After the Dharma Master carried firewood and went down the mountain, an old man sighed and said, "Zhang Ciguan's fate in this world is over." He also said to another old man, "Take half of the flat peaches that Zhang Ciguan discarded and put them on Shiniu Mountain to let him know our hard work." Halfway through. While resting in the "Changing Pavilion" in the mountains, Master Nagarjuna, the abbot of Gaoshan Ming Temple, told the details. The Master said: "Two old men, one is Taishang Laojun, and the other is Yuanshi Tianzun. The peach placed on the stone is a flat peach that ripens once every three thousand years. If you can eat it, you can fly in the clouds and travel around the world. Just eat it Half of them have not been able to escape from the mortal world for the time being, and they still have to work harder." Later, the Dharma Master went to Shiniu Mountain to shake the demons. When he saw this stone, he remembered Master Nagarjuna's revelation and knelt down at the Xiantao Stone to thank the two gods. Therefore, the stone is transformed into a flat peach. It is said that if you touch the stone sincerely, your wishes will come true.
