No, I haven't Crow. Just tried to stare into Infinity with unbending intent (as far as I can comprehend what that is, for now). That means eyes wide open and clear.

For you, does squinting also mean a kind of blurring of the eyes?
What do you mean by "improve your form"?

My initial reaction is that closing the eyes would weaken the link with the spirit, thus diminishing the amount of redeployed energy. That "link with the spirit" is a borrowed quote from my kung fu instructor

Or from another angle, in the vein of Daoism:
For Tensegrity, eyes open.
For Recapitulation, eyes closed.

Open. Closed. Open. Closed.
(For the jist of this last bit, think Homer Simpson: America. Australia. America. Australia.)

At some point (like the yin and yang symbol where the extreme of one polarity reverses itself, ie. black into white and white into black), your eyes remain open while recapitulating and closed while performing Tensegrity.
Also, the possibility that it eventually becomes irrelevant- a kind of non-duality...

You could be onto something, Crow.

Erm, that's enough rambling from yours truely! Heh, heh.
