Bankei's Miracle

KOAN:

Bankei was approached by a priest who boasted that his master possessed miraculous powers. This master could take a brush and write Amida in the air and the word would appear on a sheet of paper in the distance. Challenged to equal this, Bankei replied, “My miracle is that when I feel hungry I eat, and when I feel thirsty I drink.”
