Hi @Tranquility !! Welcome to the forum!
Do you regard the Realized One as possessing form, feeling, perception, choices, and consciousness?”
rūpaṁ … vedanaṁ … saññaṁ … saṅkhāre … viññāṇaṁ tathāgatoti samanupassasī”ti?“No, reverend.”
“No hetaṁ, āvuso”.“In that case, Reverend Yamaka, since you don’t acknowledge the Realized One as a genuine fact in the present life, is it appropriate to declare:
“Ettha ca te, āvuso yamaka, diṭṭheva dhamme saccato thetato tathāgate anupalabbhiyamāne, kallaṁ nu te taṁ veyyākaraṇaṁ:‘As I understand the Buddha’s teaching, a mendicant who has ended the defilements is annihilated and destroyed when their body breaks up, and doesn’t exist after death.’?”
‘tathāhaṁ bhagavatā dhammaṁ desitaṁ ājānāmi, yathā khīṇāsavo bhikkhu kāyassa bhedā ucchijjati vinassati, na hoti paraṁ maraṇā’”ti?
So there is a few things to be aware of with this passage.
First and formost, @sujato has gone with “(not a) genuine fact” for anupalabbhiyamāne, this somewhat obscures the aspect of the term that is suggestive of “not being found”, such that the sense of the passage is perhaps better given like:
"since you can’t pin down what the Buddha is in the present, is it appropriate to declare “the Buddha is such and such” after this life?
Secondly, the argument itself is rare, anupalabbhiyamāne only occurs here and at the related sutta SN22.86 (the SA parallel refers to Yamaka by name, and SN44.2 is merely a reproduction, and Yamaka itself appears to copy and paste from Anuradha, giving the view as one about a monk, but giving the argument as being about the thathagata, as in SN22.86).
A more detailed argument is given at MN72 where existence, non-existence, both and neither are compared to the cardinal directions and the question “what cardinal direction did the fire go when the fire went ‘out’?”. So in that version of the argument it is never suggested that the fire is “not a genuine fact” or that it “cannot be found in the present” or anything like that, it is clearly the case that the argument is about the applicability of concepts of existence AND non-existence to things beyond their “range”. This more common argument is obscured by the rarer one, which IMO may be the glimmer of the beginnings of a kind of tathagatagarbha type of doctrine where an ineffable, indefinable or unspeakable buddha nevertheless “exists” beyond existence and non-existence.
But it literally is about negating that view, that is the view that is negated.
It does so IMO with a weaker and less coherant argument than the one at MN72, but in no way can it be read as endorsing a view of “a kind of non-existence/non-experience”.
Good luck with your journey.
