Re: When you bow do you worship or just...
I bow out of respect.
And I don't mean only in the dojo. If I walk down the street and meet someone I know and have respect for I bow slightly (more of a nod with the head, maybe a slight forward motion of the upper part of my torso). That accompanied with a kind word is my personal way of greeting people (I should perhaps mention that bowing, even as slightly as I do it, is no longer a part of greeting patterns in my country - as it is not in most of Europe). For me it says: "Respect." Nothing more.
A proverb comes to mind, I think it's chinese, says: "If you bow at all, bow lowly."
