Aggi-Vacchagotta Sutta - Dabba Sutta

Dabba Sutta

The Udana's Dabba Sutta makes use of related imagery:

Just as the bourn is not known

Of the gradual fading glow

Given off by the furnace-heated iron,

As it is struck with the smith's hammer,

So there is no pointing to the bourn

Of those perfectly released

Who have crossed the flood

Of bondage to sense desires

And attained unshakable bliss.

— Dabba Sutta, Udana VIII.10

In this case, the simile of the first four lines of the original Pali is obscure, and the above translation is only tentative regarding its intention.
