"Self-liberate even the antidote."
In considering this Lojong slogan, I learned some Latin - reductio ad absurdum.
This is the formal term for following an argument or line of thought to the point at which the argument results in some kind of absurd conclusion. It's usage in philosophy is to point out the fundamental flaw in some argument. In common language, "it's a slippery slope". Taking one step in a particular direction makes it more likely that one will keep going in the same direction until one eventually jumps off of the proverbial cliff with their proverbial friends.
Pema Chödrön's commentary cautions us that being attached to nonattachment is folly. Yet, if one assiduously follows the teachings of nonattachment, that would surely be the outcome. In Buddhism, however, there is a safety buffer against this - the Middle Way. The site zen-buddhism.net puts it this way: "By 'middle', Buddha essentially meant that we need to embrace both spiritualism as well as materialism, just like the front and back sides of a sheet of paper." (love that image)
The Middle Way is a great protector against the human tendency to drift toward extremes. The idea that there is one right way to do or think about something is both comforting and seductive to us. The Middle Way on the other hand is messy. Everyone has a different idea about where to draw the line against absurdity. It takes prajna remember to analyze the pro's and con's of sustaining a given principle, especially when that principle is intertwined with your personal philosophy of life.
Lying is wrong. Don't lie. Still most people would likely stop short of ruining a surprise party for a friend even if entailed telling a lie. All people have a right to health care and should have equal access to care. Still if the health care providers go out of business or are starved for resources, no one gets adequate care. So...what do we do? That one's harder, right?
As usual, this is where Buddhism throws the responsibility for our enlightenment back on us: our thoughts, our views, our actions. There's no out for us by simply leaning on some general principle and continuing to repeat it. Man, who knew being awake would be so much work!
