Bhadrapala, and sixteen awakened lords who were his companions, arose from their seats and bowed at the Buddha’s feet. He said to the Buddha:
”We first heard the dharma and left the home-life under King of Awesome Sound Buddha. Once, when it was time for the Sangha to bathe, I followed the custom and entered the bathhouse. Suddenly I awakened to the fact that water does not wash away the dust, nor does it cleanse the body. At that point, between the two, I became peaceful, and I attained the state of there being nothing at all.
To this day, I have never forgotten that past experience. Having left home with the Buddha, I have gone beyond learning. That Buddha named me Bhadrapala. Wonderful touch was revealed, and I accomplished the position of the Buddha’s disciple. "
