Bhante, I am happy to agree with what you have very clearly stated. I would also like to add the following:
If we say the Tathagata exist after death which Kandha are we refereeing to? As the craving has been completely eradicated, (unlike in other sentient beings), there is no base for the five Kandhas to continue to manifest. Even though the Kandhas are present, (in the present life), they are not subject to the power of seamstress, the Craving.
In MN 22 Alagaddūpama Sutta, Lord Buddha discoursed that Tathagata cannot be found even in the present life. Here is that section:
“…………….When a mendicant’s mind was freed like this, the gods together with Indra, Brahmā, and the Progenitor, search as they may, will not discover: 36.2 ‘This is what the Realized One’s consciousness depends on.’ 36.3 Why is that? 36.4 Because even in the present life the Realized One is not found, I say……… .”
When the Tathagata cannot be found even in the present life, what more of after HIS death?
In another Sutta SN 44:11 Sabhiya Kaccāna Sutta, Venerable Sabhiya Kaccāna discoursed to the wanderer Vacchagotta:
“ 3.14 “In order to describe him as ‘possessing form’ or ‘formless’ or ‘percipient’ or ‘non-percipient’ or ‘neither percipient nor non-percipient’, there must be some cause or reason for doing so. But if that cause and reason were to totally and utterly cease without anything left over, 3.15 how could you describe him in any such terms?””
