In case it's not clear, I didn't say that...
Also, I should probably clarify. The 'talkative' sensei I study under at Carleton does /not/ lecture about 'religion' or even 'spirituality' per se. Judging by his other remarks, he'd find that inappropriate - which I agree with entirely. (It'd be overstepping his bounds, and would make students uncomfortable.) When he lectures, it's advice on things, like "This is an abrupt ukemi; suddenly you have to back breakfall. I find in life, sometimes you have to change direction suddenly as well..." I think that is "fair game" for sensei.
