Slightly off topic, or at least on a tangent...
A male aikido teacher, who we may call Jack, ran a dojo for many years together with a female teacher of equal rank. He told me about a student of theirs who went to some kind of coaching seminar for sports/martial arts. The teachers at the seminar talked about female and male leadership styles, listing features of each leadership style on separate sides of the whiteboard. The student said "It matches perfectly! How I recognise these two styles - only this is Jack and that is Joan."
It was my impression that he truly cherished that story.
I love this story, it's like describing the opposites of uke tori, teacher student, male female, wright wrong, good and bad, up and down left and right, Ki aikido or yoshinkan aikido, good teacher bad teacher.
in the end what is left, are only students of the way, any distinction is only semantics, and each one is born of the other, and they indeed compliment each other perfectly and in harmony.
It is only the ego that makes you believe one is more virtuous than the other.
