Hi guys. Sorry about not responding sooner.
I went back and listened to the first half of Ajahn's dharma talk repeatedly since yesterday. The central point he was trying to make is that mind-states are composed of 3 factors, mainly- which he referred to as feeling
(of meaning) and then he used a pali word i couldn't catch, sounded likesankara
? He purposefully used that term in a limited way to refer to reflexive patterns of activity
that arise psychologically- in our minds- prior to our carrying the behaviors out. Here's the first 14 minutes of the talk...
I took some notes (below) to try and clarify, because sometimes Ajahn used terms (like feeling) in more then one way. Also, while he talked of "feelings" as being first he later said they are triggered by perceptions, so here the 3 factors are again with a bit more detail, and reordered, putting perceptions first, feelings second and response patterns third.Mind-States are made up of 3 Inter-related factors
1) Perception- We take in information from our environment and interprete its meaning, to us- friendly/unfriendly, safe/threatening
2) Feelings- Once we have arrived at a perception of meaning feelings are triggered, chemical rush of emotions such as pleasure, displeasure, fear, anger, sadness, joy, etc.
3) Response Patterns - Our feelings and perceptions then activate response patterns, what to do, how to react and respond to the situation. Flight or fight, argue, go lie down, push away, hug, scream, walk out the door. These are patterns of behavior which first arise in the mind and then activate actions in the world.
He then goes on in the talk (linked in the OP) to speak about how our role as meditators and practitioners is to observe these psychological factors arising and learn to *not* react, not act in knee-jerk ways, recognize also how a sense of "self" is created by the above- through our identification with these states of mind.
The MRI scans I presented of brain patterns relates to all the above but most closely to this last area, and also how our minds shift into different feeling/perception/activity patterns throughout the day...
BUT my point was tangential and is not as important as Ajahn's focus here, imo. Please just ignore these images if they are not helpful and don't fit with your understanding.
