Sakyamuni said, "I'm willing to offer you my body as food, but first tell me the two lines."

Indra refused. "No. First I must eat you to build up strength. Then I will tell you the two lines."

Sakyamuni replied, "But then I'll be dead. I won't hear what you have to say."

Indra said, "Let's compromise. You stand on top of this tree. I'll stand below looking up, and you jump into my open mouth. I'll tell you the two lines as you are falling through the air."

Sakyamuni decided it was worth it. "My body might die, but hearing Buddhadharma is more important. I'll do it." He climbed to the top of the tree and jumped. Indra kept his promise and recited the two lines. Sakyamuni expected to land in the demon's jaws, but instead he found himself on the soft cushion of Indra's palm. Thereupon Indra revealed his true identity and told Sakyamuni he had come to test him.

What were those two lines? How badly do you want to know? Is your pursuit of Buddhadharma sincere? If you jump off the roof, I'll tell you before you hit the ground. Perhaps you do not yet have the courage of a Bodhisattvas. However, since you have come to a retreat to practice, you must be relatively sincere, so I will recite the last two lines:

When the Dharma of arising and perishing itself perishes,
Nirvana is the greatest joy.
