yes… we are all believers , but I find it interesting that something that is so fundamental in Proper Theravāda is not mentioned everywhere. where it systematically goes through each khaṇḍa for each sense door and sense object. You have to look hard, but there is only one thing here or there… for instance exclusive to saññā , shhh… don’t want to tell suttantas this.
But … i’ve listened to a few talks by westerners on the khaṇḍa and they don’t mention the sense doors. I’m thinking… how can you explain without the sense doors. khaṇḍa of what? is my thought.
