Hey L
Great going!!
5. Can "you" be found through the direct experience of any of the senses?
5. No, it's more like circling around a hole looking for a building that should be there
.
This made me smile.... a lot :)
Since you are quite clear that the senses are not able to clearly reveal a you, let's turn our attention to the other mode of knowing about reality, which is thoughts and thinking.
You have also already taken a cursory look here, so let's deepen it.
Firstly you can directly experience a thought. To clarify I mean you know what a thought is without doubt. Just as you know what a sound is.
Thoughts in themselves are really just pointers or labels. They label objects, actions, concepts, relationships...whatever.
When a thought refers to a cat, or a building, or a tree - these are objects that have physical reality.
Then thoughts refer to things that exist only in concept, such as a belief, a legal framework or an ideology.
When your thoughts refer to "I", or "L" or "me", you have already seen that this is just an assumption, a concept - there is no solidity or reality to this self.
Please let me know if you are in agreement so far.
Your thoughts about yourself that build this narrative, make a very heavy assumption that there is a real you that the narrative is built around. It is only when you question the assumption that you see that there is just a hole...no building.
So since a tangible you cannot be found, who is thinking these thoughts? Are they your thoughts?
The thoughts are weaving a story about an imaginary you, a fictional narrative indeed. Are you the one creating this story?
