Currently I’m reading "La marche à la lumière – Entretiens du Bouddha"[1]. What is laughed at here precisely describe what the Buddha is making through the whole book. While apparently, just like Socrate, Buddha didn’t let any directly written legacy, it’s clear he has been attached to the notion of an egoless person discussing the topic with whoever would like to ask about it.

Now of course it doesn’t necessarily mean that the person laughed at went through some accomplishment. But whether they did or didn’t is not relevant. What matters here is can it be believed that some human accomplish an egoless experience of life and still continue to discuss with people who didn’t.
