This is very interesting stuff for me.
Yesterday I was experimenting with perceiving anothers thoughts,
as it was mentioned in another post that we can perceive such emissions,
before the opponent even consciously realizes his/her own intentions of physical act.
This experimenting really concretized the truth of this for me.
When I did not think with mind...when my response was simultaneous to the others delivery or PRIOR to it, I found success repeatedly. The instant, I paused, even a second, thought or tried to visualize in depth or superficially, of the others thoughts, I failed...repeatedly.
Empty mind really does remove the "interference" the mind and heart imposes on..."the spirit",
or wuji's no minddness...which really is very efficient.
I understand what you are saying about spirit...and it's connotations...It is something I continue to ponder. Not an easy entity to define or grasp. For practical use in TaiChi, I simply consider it as the no mindedness we find, once we abandon mental thought...but great dissertation could be had upon this word, I am sure.
These quotes are excellent for ponderation...thank you for sharing them, each time I read them I find a new thought.
Great thread! I have been following avidly.
