Johnny:
A comment on your first entry here.
If one starts off with the contemplation of any one of the three, the other two will follow. They are three aspects or manifestations of one thing really.
My own experience is this: seeing the anicca nature, (1) and the suffering that that causes through the sense of unsatisfactoriness and therefore the disappointment that is there (2) can this be what ultimate existence is all about EVENTUALLY? (3). And the suffering here is only the one we experience now in this life, not the dukkHA that extends into future lives, the contemplation of which strengtens the relevance and meaning of Anatta even more.
In my case,it is seeing the Anatta nature in its sense of imperfection that comes naturally. 3) first, followed by 2), and then then 1). But the three are really one.
As a child I used to ask, myself and others: ‘Where is perfection? everything I see here is imperfect’ The reply from my parents ran something like: ‘ are YOU perfect?’ Naturally, I knew I was not. The implication of course was: first become perfect yourself, then you will find that Perfection. So with me, even then, the first I saw was the Anatta nature, without of course refering to it by that word.
Now all that has come to have meaning AND purpose.
