Danxia Tianran traveled to meet with Great Ancestor Ma. Upon first seeing one another, Ma had a good look at him and said, "I am not your teacher," advising him to go to Shitou's place. Danxia made the long journey and joined Shitou's community as a layperson, working in the stables and temple kitchen for several years.
One day Shitou announced to the assembly, “Tomorrow we're going to clear away the weeds in front of the Buddha's shrine.” The next day everyone arrived equipped with tools to cut down the weeds. However, Danxia showed up with only a bowl, filled it with water, and washed his head; then he knelt in front of Shitou. Laughing, Shitou shaved Danxia's head for him, in preparation for taking refuge in the Way as a monastic. As Shitou began to confer the precepts, Danxia covered his ears and ran out.
Danxia then journeyed back to Great Ancestor Ma's place. Before meeting with Ma to pay his respects, Danxia went to the monk's hall, climbed onto the large statue of Manjushri, and sat astride its neck. Everyone became quite upset, and some hurried off to tell Ma what was going on, who then came to the monk's hall to see for himself. Seeing Danxia upon the statue, Ma smiled and said, "Ah yes, my son, so natural."
Danxia climbed down from the statue, bowed before Ma, and said, "Thank you, teacher, for giving me my Dharma Name" (Tianran, which means "natural")
