Thanks everyone!
I would not like to sound as a sophist trying to artificially complicate the issue but it still remains. It has been almost a year now that I study Dhamma through different sources and the “Anatta” principle never caused any serious questions and doubts. On the contrary it was for me quite a fundamentally critical and important understanding of human nature, as we naturally assume something constant as a “soul”.
I would like to return to the main question and issue that I have risen here to point out that it is quite simple schema, where presumably problem lies. It is not a linguistic complication, sophism, etc. I can not just follow the “path” as suggested without clearing up this issue.
So, again, I say:
If “Anatta” principle negates any inner constancy and declares even the “Self” impermanent
If that is true, then
On every occasion when this impermanence is observed there is an OBSERVER that sees and points out to that impermanence (meaning turns what is observed into subjective experience)
Even when I say that “THERE IS no self or THERE IS impermanence” I already point out to something other than ME; I observe that there is no “I”
Nothing can be observed if there is no OBSERVER, a WITNESS to a process
You only see a movement/process relative to non-movement (rest). So, there should be something FIXED to point out to something MOVING/CHANGING
Again, all of the above mentioned is not just logical speculations. It can be observed during the “Anapanasati” as well. It happened all the time, when “I” observed thoughts rising and dissolving. There was an impermanent process of thought-making but there also was the one seeing that process.
I would much appreciate experienced people to help me with this issue. If I misinterpret “Anatta”, then, please, provide me with some sources that would clear the issue. Thanks!
