Aggi-Vacchagotta Sutta

[2] Vacchagotta first asks the Buddha whether he holds particular views on the extent of the cosmos, the relationship between mind and body, and the nature of a Tathagata's existence after death.

[3] A tathāgata has abandoned that clinging to the personality factors that render the mind a bounded, measurable entity, and is instead "freed from being reckoned by" all or any of them, even in life.

[4] A variety of similar passages make it clear that the metaphor "gone out, he cannot be defined" (atthangato so na pamanam eti) refers equally to liberation in life.

[7] The fire metaphor used in the Aggi-Vacchagotta Sutta (which is also used elsewhere) is a radical way of making the point that the liberated sage is beyond phenomenal experience.

[8] The Udana's Dabba Sutta makes use of related imagery: 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.
