A bird flew into a temple one day and couldn’t get out. The bird flew from window to window, battering himself in a vain effort to escape. Then, exhausted, the bird rested on the windowsill of the only open window…without realizing it was actually different from the others. A teacher, who happened into the temple toward the end of the bird’s efforts, and observing the difference of the windows was not known to the bird, clapped his hands. The startled bird jumped through the window and was free.
