A great exploration of the concept.  Really vivid.  The expression of the piece is superb.  There’s a few breaks in the flow of it (some rough direction changes and introductions of supporting thoughts without a segue to bridge them) but it’s brilliant.

You lost me.  Sometimes I think I am too logical.  Here are the problems I ran into:

“That a child’s clairvoyance works as a mirror in which one sees some crossed hurdle is a matter of my personal experience.”

I pondered this sentence for a while because I didn’t understand it.  The child knows of the hurdle, I guess, which is what the clairvoyance is all about.  So, “works as a mirror” means that it shows the author the hurdle.  What confused me is the idea of clairvoyance itself working as a mirror.  It’s really the child working as the mirror because of his clairvoyance, right?

In the little story of the man and the boy and the girl and the young fellow, I was busy painting this picture in my head and I got confused.  The boy “looked back” at the fellow, so I think the fellow was behind the boy.  The boy then turned around and fixed his sharp gaze on someone’s face, but it isn’t clear who.  After thinking about it, I conclude that it must be the father’s face, but maybe after the boy glanced back at the fellow who then smiled, he faced forward for a moment before turning around again…

In any case, these are just examples of structures in the piece that confused and distracted me.  I like the idea of the tiger of life, and I think there’s something in this piece that can help me, but I don’t see it clearly.  I can’t tell if that’s because I’m confused by some of the writing or because it’s something I’m not prepared to consider about life and/or myself (though such things are rare AFAIK).
