just a comment, maybe that you know all of this, but I will try to put it in another manner.
IMO, choice, in practice is called manasikara (direct attention to, turn towards ,..)
good (or skilfull) choice = yoniso manasikara
bad (or unskillfull) choice = ayoniso manasikara
MN 19 : Dvedhavitakka Sutta: Two Sorts of Thinking http://www.accesstoinsight.org/tipitaka ... .than.html
MN 20 : Vitakkasanthana Sutta: The Relaxation of Thoughts http://www.accesstoinsight.org/tipitaka ... .than.html
how does one arrive to decide that this is yoniso manasikara or that is ayoniso manasikara ?
- by knowing what is greed/aversion/delusion (lhoba/dosa/moha)
and knowing what is non-greed/non-aversion-non-delusion (alhoba/adosa/amoha)
and seeing & feeling the (bad/good/neutral) results of such and such actions/speeches/thoughts under these mentals, happened on you or others.
after that, with compassion , do in the direction of what is considered to be yoniso manasikara.
that is, IMO, the key that one can and must see.
see AN 3.65 : Kalama Sutta: To the Kalamas http://www.accesstoinsight.org/tipitaka ... .than.html
Now we are luckyly met the unsurpassed instructor of deva&human being that show us the right direction to see.
The paticcasamuppada can be seen from different angles. When one is not at least sotapanna, one must remind that most of his reaction is conditionned by ignorance-Avijja and/or graving-tanha. And tanha is conditionned by vedana. Vedana is a result that we cannot avoid. But we can "deal" (if you don't like choose) in an "ayoniso-manasikara" manner that causes tanha (then dukkha), or in a "yoniso-manasikara" manner that cuts the arising of dukkha.
ignorance-avijja can be dispelled by studying/hearing/reflecting on this Buddha-sasana and practising in accordance.
So what is the Buddha path ? that is the 37 Boddhipakiyadhammas. and between them if one "wants" to "obtain" the goal for which he followed the path of this Buddha Dhamma, one need to cultivate the "Four bases of power" (desire, persistence, intent, discrimination). Why ? because according to the universal law of kamma, and it is obviously that one will obtain an expected result/effect if one desires/reflects/makes efforts to create conditions that allow it to happen. You should note that "Four bases of power" come after 1/ Four frames of reference 2/ Four exertion. Surely that in this BuddhaDhamma, understanding Dhamma comes first which will lead one to the correct practice without unnecessarely over-thinking about no-self : as the Bouddha advice : practice and see for your"self" http://www.accesstoinsight.org/lib/auth ... part2.html
Only the arahant has completely liberated from the sense, the feeling of a SELF, remember why the Buddha did teach anatta only after that the first 5 bikkhus had attained sotapanna ?
So where are you now on the path ? I think that there is no need to over-thinking about SELF or NO-SELF : just letting go , otherwise the dhamma anatta will become a concept of anatta, then an attachment of the anatta-view. In fact, this is a SELF-VIEW on the NO-SELF concept if one does not attain sotapanna.
Just check out if in a practical way, does one practice with letting go - upekkha - by reflecting & undestanding that "this is not mine, this is not I, this is not my Self" ?.
If one pratice diligently then one day, this will come true within him :
there is action , but no actor
there is choice , but no chooser
there is kamma, but no doer
there is path , but no walker
just my two cents
