Of course my interests are in how this all fits with the "MMPs" (multiple mortal probations - of "worlds without end") and how our "created" (God simulated) world is ultimately a place where our spirits choose to locate themselves and obtain this Godhood enlightenment.
I read the whole discussion over there and I do find it interesting -- although probably not interesting enough to go out and read Lowry.
I think one of the big things that keeps me from delving too deeply into Buddhism is that I very much enjoy my "interests" that I create for myself. I enjoy both the selfish interests and the altruistic. And I admit that a certain amount of control over these interests - especially the selfish one's - is a very important thing we need to learn to accomplish in this life.
And I agree with the idea that without these attachments (we create for ourselves) there would be no pain. I would disagree (with the interpretation Yasiru gave) that James meant to say without pain there could be NO pleasure. I would rather interpret that he meant the pleasure would be empty without pain. Or, maybe he meant that that the pleasure of such perfect "oneness" with the universe would itself be empty -- and would not result in the "Sansāra" or bring an end to the endless recycling of birth and death. I will let James speak for himself.
I think this "check out" philosophy might be a helpful one to some souls who have come to this mortal world with extremely struggling or troubled spirits, and those who have entered this world to obtain what their spirit might personally need on their particular path to enlightenment. (remember the movie "Groundhog day")
(By true enlightenment, I am talking about one's ascending to that higher plane, or to make the break from the sansāra or sangsara of having to live so many multiple mortal probations)
I choose to enjoy this life. If I am living in a created world for my benefit, then the pain I feel is also for my benefit. i.e. when I prick my finger, it hurts. Therefore, I try to avoid pricking my finger (we won't get into George Carlin's "fingering my prick" philosophy).
One of the things we might obtain here for our "enlightenment" -- is the ability to recognize and remember those people and things we have learned to love - for this wold and for the worlds to come.
Can we love without knowing hate? Can we have pleasure without knowing pain? Can there be light without dark?
I think yes. But, what would be the point? This "fallen" world concept is consistent with the plan of salvation. We could move on from the Sansāra without knowing or conquering pain -- but, what would be the point? That is all I think James was saying -- and I think it was appropriate for him to point out in his book review that Siddhartha Gautama did not necessarily say that knowing pleasure or pain was always a bad thing either. We can try to be like Bill Murray's Character ("Phil Conners - "Punxsutawney Phil") and just "sit this one out," but, in order to reach true "enlightenment" we have to face our fears and our pain to internalize our desires rather than be driven by them.
We can build maze solving robots with no central processing (only sensors and motors). Alas, they never know the joys of their struggle to complete the maze.
