13.4.p10

“The Bhagavān then told me, ‘So it is, wealthy man. This body has many infirmities, and it has just this thin skin covering it. Wealthy man, you should know that, even when momentarily happy, one who relies on this body doesn’t know the long night of suffering they’ve experienced, which is measureless. Therefore, wealthy man, though this body has its troubles, you should make your heart untroubled. Thus, wealthy man, you should train yourself.’ That was how the Bhagavān watered me with the Dharma of ambrosia.”
