Firstly...I'd like to agree at the potential value of the I-Ching...Quite the multi-faceted tool, from what I have gleaned of it so far.
I feel your frustration and wish I could help with your questions...But I know naught of Rutt or his works.
There are many questions asked on this board and not all produce answers...For whatever reasons...
Just a handfull of flawed human beings here-as everywhere.
(no offense to all those flawed human beings out there).
Including varying developing girths of mind set, different perspectives, different opinions...
Some opinions could/should/might be delivered more delicately...as they ARE only opinions...Especially those opinions including judgements of a persons being and his qualifications or aptitudes...Personal judgements as it were.
Anyways, David, why worry if someone disgrees with what you state...or even if they refuse to even listen...The answers will surely find their way to you if you are seeking them.
These are only MY opinions...
Good luck in your search.
