“From reading the posts it seems dhamma can also come from the mind while produced in javana citta?”
That statement does not make any sense.
– Just like rupa (sights, sounds, smells, etc) come from the external world, dhamma (memories, kamma vipaka, etc) come from the external world. One is a “material world” and the other is an “immaterial world”. That is explained in one of the posts I recommended for you in my previous comment.
– We can see a tree out there or that a sound is emitted when two objects hit each other or that a certain odor is emitted by a flower… But dhamma cannot be “visualized” that way.
“I think it needs some attention to explain how it is possible that the experiencing or sensing happens around the heart-region, while we clearly experience all kind of things like emotions, memories, thought in our head?”
– That is because you have not read the posts carefully.
– In recent posts, I have explained in detail how the brain is “working overtime” while watching a movie, for example. It has to process sights coming through the eyes and the sounds coming through the ears continuously while watching a movie.
– That is why we may get a headache if we watch two movies at a stretch.
– And that also explains why we have the perception that thoughts are created in the brain.
On the other hand, when we hear traumatic news like the death of a parent or a child or a spouse, we feel that close to the heart. Those feelings are felt in the hadaya vatthu which is located in the mental body overlapping the heart. People say, “my heart became burdened”.
– In especially joyful instances we also feel that close to the heart, not in the head. People say, “my heart became overjoyed”.
