M. Ueshiba learned Takeda's aiki skills and then, because of those skills, it opened a different spiritual door for Ueshiba.
Generally, I dont disagree with your balanced appraisal. But the above sentence strikes me as requiring some explanation. "Aiki-skills" TM were the doorway to a "different" spirituality for the founder? What evidence is that based on? Different from what? Would you expand?
Interesting discussion everybody, thanks.
