You should sleep

Chan Master Gasan Jōseki (Japanese: 峨山韶碩, Gasan Jōseki) sat at the bedside of his teacher Tekisui (Japanese: 鉄水, Tekisui).

Three days before Tekisui would die.

Gasan had already been designated by him as his successor.

A temple had recently burned down, and Gasan was working tirelessly on its reconstruction.

Tekisui asked him:

“What will you do when the temple is rebuilt?”

Gasan replied:

"When you are well again, you should teach there."

Tekisui asked further:

“And if I am no longer alive by then?”

Gasan said calmly:

“Then we will find another teacher.”

Tekisui asked again:

“And if you can't find another one?”

Gasan replied loudly and clearly:

"Don't ask such foolish questions.

You should sleep now."
