Arañña Sutta
The Wilderness
Translated from the Pāli by Thanissaro Bhikkhu
Standing to one side, a devata addressed the Blessed One with a verse:
Living in the wilderness,
staying peaceful, remaining chaste,
eating just one meal a day:
why are their faces
so bright & serene?
[The Buddha:]
They don't sorrow over the past, don't long for the future. They survive on the present. That's why their faces are bright & serene. From longing for the future, from sorrowing over the past, fools wither away like a green reed cut down.
