Thanks Ian for your helpful assessment! I've only been on DhO for 4 or 5 days and I already feel at home

Ian And:
Generally speaking, you're in "access concentration" when practicing samatha (tranquility) meditation when you are able to remain focused on the object of meditation for at least 3 to 5 consecutive minutes or more (10-20 minutes usually indicates jhana) without becoming distracted or without unnoticed distraction.
One thing that's been confusing to me in terms of analyzing my meditation experiences are the thoughts that I have while concentrating on the breath. I know that complete absence of directed thoughts is not something to expect until reaching at least the second jhana. But I guess what's confusing is which thoughts count as "distracting" thoughts.
For example, here are some verbalizations of a few common thoughts that arise while I'm in concentration:
1) "I'm observing this part of my body"
2) "This part of my body is doing this."
3) "Now I want to switch to observing another part of the body. Here I go."
4) "Wow, I'm really doing a good job at concentrating right now!"
5) "Now, if only I could maintain this state for a few more minutes..."
6) "Hm, I wonder if what I'm experiencing right now is what the Buddha was talking about when he described [x, y or z]?"
7) "I feel really comfortable right now. This is nice!"
Which of these thoughts are inherent, or at least common, in, say, the "directed thought" of the first jhana? Which, if any, are considered not inherent in first jhana, and/or distractions to be noticed and then let go of?
Since my immediate goal at the moment is reaching the first jhana and dwelling there for an extended length of time, I ask this in order to know which kinds of thoughts to allow to effect my experience, and which to simply let pass.
For example, when the thought arises "now I'd like to switch to observing the nostrils, instead of the abdomen", should I 'listen to' that thought, (i.e. start observing the nostrils), or should I just let it pass without listening to it?
Or, by looking for such a distinction, am I missing the point?
Thanks again for you help. I hope I'm being clear in what I'm, asking.
