Thank you, Lal!
“It is just that the “sweetness” or “saltiness” in not a vedana but a “sanna”.”
This makes a lot of sense!
So, the nature of “sweetness”, “saltiness”, etc. is the “Guṇa” part of “Kāma Guṇa“. If we were to invent a phrase, can we say that an arahant has “Guna Sanna“? (with guna implied to apply to the kama loka).
If we say “Kāma Guṇa” then the “Kāma” part implies some kind of attachment, and not mere “qualities” or “characteristics”, correct?
