If I was the king of the world, I'd mandate that Westerners start with a decade of strict Theravada _practice_
Dear PT -- Crass (but apt) phrase alert!
There used to be a saying that went something like, "he's so dumb, he'd f*** up a wet dream." And I imagine that any one of us might be accused of the same. In my view, there just plain does not exist a thing that is so good or true or warming that it cannot lead a person down some silly or painful garden path: It is the individual, after all, and his or her understanding or misunderstanding that counts ... not the thing that is so good and pure.
To my way of thinking, people choose their lies. Maybe very good lies, maybe very deluded lies, maybe some mixture ... it depends on the individual, not on the praise or blame that anyone else might heap on the lie. But the important part of this scenario is not the cringing that may follow the use of the word "lie," but the willingness, based on honest-to-goodness suffering, to get to the bottom of that lie ... to see things through ... right down to the truth.
Buddhism is not built for people who get things right. If they got things right, why would they bother with Buddhism in the first place? I simply don't know a practicing Buddhist who has not made and who does not continue to make mistakes ... sometimes things that can be corrected, sometimes leading to some very profound psychological misadventures. But whatever their mistakes, the imperatives of suffering mean, for many people, that they feel they must choose some way to find relief. Sometimes they choose wisely. Sometimes not. Either way, there is suffering and a longing to end that suffering.
Is Buddhism a better choice than, say, skeet shooting? Maybe so, but I have not consulted with the skeet shooters of this world, so the fact is I don't honestly know. I do know what I have chosen. I do try to avoid subtle and gross mistakes ... and often fail. But is there a fail-safe way, even in Buddhism? I doubt it. There is just this effort, whatever it is. There are pointers from good friends and a number of enemies, but in the end, there is just this effort ... and a hope that I will see things through for once in my life.
Sorry for all the blither.
