It's when they become unpleasant that the challenge begins. It's at that point where accepting it for what it is does not make sense to a increasingly displeased "I". I realise I'm just rehashing things I've already stated before, but I'm stuck on this point.
You are stuck because of the way you look at "acceptance".
Is this getting close to how you think acceptance should to be working:
When everything is fine I am happy to accept this moment as is, but when things happen that displease me then acceptance is an effort that runs counter to what "I" would like to do...
But... maybe its never an "I" that does anything in the first place... maybe its just a thought that says "I have moved away from this stinky place because I don't like the smell even I should be accepting enough and not worry about the smell... I have not realised no-self yet because I can not accept every situation as it arises!"
BUT: Accepting something is not an effort. If something is wrong or painful you move out of the way, thats it. No reason to prolong the situation only because you want to be accepting or impartial. When a bird smells fire it flies away. No need to stand your ground and be burnt. There is no thought about acceptance, it simply happens. This is what I meant with "you simply accept it for what it is".
When something is unpleasant then the next action will be to avoid this situation - not to sit and endure only because "you" deem that necessary to achieve a certain state of realisation... When you are in severe pain there will be thoughts about how to avoid the pain. These thoughts might result in you getting up and taking a few painkillers... No problem with any of that, right?
There will also be thoughts about how poor you are because you have to suffer so much... so are these thoughts any more problematic? Do they mean that there really is an I that is suffering? Is there an entity that suffers or are there only thoughts about this entity, an entity that can not be found outside of these thoughts about it?
So, yes, by getting lost in these kind of thoughts you add psychological suffering on top of the physical pain - the pain is real, the suffering is just a story... Can a thought suffer? Or can there be only thoughts ABOUT suffering?
if realisation of no-self does not exclude the entire range of human emotions (including anger), it will also not exclude the range of actions that could stem from these emotions, some of which have nothing to do with generosity, compassion, integrity, humility and various other traits that resonate with me and which I've always considered a natural state of one who is "in truth"
Realisation of no-self is simply the clear seeing that there is no such thing as a separate I/self. It has nothing to do with favouring certain emotions or actions over other ones. This is the natural outcome of knowing who/what you are, not of the realisation of what you are not.
Maybe what you are after is not the realisation of no-self... you might be on the quest of "What am I?" (if not this separate self).
At first glance they seem to be identical, but if you look closer then no-self seems to imply that you have to drop something, something called I/self... When looking at "What am I?" you might have already seen that I is just thought, so you are not this separate entity - you have realised no (separate) self... but does this solve your question of "What am I?'?
So... Who is the one "having" all these emotions? Who is doing these "actions"? If its not this separate I, then who???
Look at this experience - look, hear, smell, feel, think. What are you? Is there something like a "you"? Or is "you" just a certain perspective, a (thought based) point of view? An imaginary onlooker... looking at what?
What are you looking at when you see your body, others, the world out there?
