I don't know how to translate it into English, but it's spelled:
in Chinese writing. It's that particular type of crossed-legs sitting stance of the Buddha. (And mind you, it's also different from the crossed-legs stance many of you Asian people might be accustomed to.)
If you know how to do it, stick to it. Good for the health of your lower back.
If you don't know how to do it but can see me offline, ask me how to do it next time you see me. I'll show you.
And no, it doesn't have any strong Buddhist (or religious) implication. In other words, doing it doesn't automatically render you
committed to Buddhism or the whole set of Buddhist precepts.
