Interesting human phenomenon, the notion that because I have learned some hard lessons, cut my way through one thicket or another, somehow others should not be required to do the same. All I have to do, for example, is tell someone my conclusions, they will listen and hear ... and they won't have to raise a sweat on that subject.
Parents, if they're anything like me, do this all the time -- hoping against hope that their accrued wisdom can somehow be passed into their children. No parent wants his or her kids to be lonely or sad or too cocky ... so there is the effort to point out the hard lessons the parent has learned. No one who has been to war (short of psychotics) would wish such a thing on anyone else. The experience is just too horrific, too compelling, too wounding even when you set aside the physical wounds. And in spiritual endeavor the wish is the same -- that all those tears and all that sweat will have some meaning and that that meaning can be transmitted.
But there is one more hard lesson that goes with all the other hard lessons. It cannot be transmitted, no matter how ornate or intricate or sensible the explanations. Kids have to go through their own thickets; the wounds of war serve little or no wider understanding; and the mounds of wisdom collated in books or minds will not suffice in spiritual endeavor.
The hard lesson is -- experience cannot be shared. And that can feel pretty lonely right up until the moment that its factual nature is accepted. The fact that experience cannot be shared does not mean we cannot converse or point out the particulars of a problem. We don't have to be stupid or heartless. But that pointing out is not the same as the experience of a particular thicket -- a thicket that may rip the skin off your heart or fill you with an unspeakable peace.
I guess the bottom line of the fact that experience cannot be shared is something like, "Patience!" and "Get over yourself!"
Why anyone invented koans when there are living situations like this ... well, it beats the hell out of me.
