Zhang Jushi was a clerk in the Song capital, and his taboo name was Daochun. His wife, née Ma, left the household (for religion), and founded an Academy Assisting The True Way in Huzhou City. Firmly dedicated to the Way, she lived on Fangzi Alley, off Xiuwen Lane, and opened the Pharmacy to Academy Assisting The True Way, in the gengchen year of the Zhiyuan era (1280), and often provided meals to Buddhist and Daoist monks. One day, having first distributed 100 tickets for vegetarian meals, when the day came these were taken as evidence for those attending the food provision. As the time approached, however, the tickets collected amounted only to ninety-nine, so they were missing one. Jushi paid without asking, and therefore provided ninety-nine percent of the meals, but this left him feeling less than entirely satisfied. The next night, he dreamed that a Daoist came to report to him: “The ticket is with me, Guai.” On awaking and reflecting on this, he realised that there hadn’t been a ticket made out to Master Guai, so went urgently and found a boat to the Daoist temple from the pavilion over the well. Knocking at the temple gate and looking, he indeed daw that (the statue of) Guai bore a meal slip, and inscribed upon it were four sentences:
Going especially to receive a meal
I saw that I was not dealt with.
My meal-ticket tied to my staff.
He thus understood that immortals also attend worldly alms feasts.
