What I do is actually teach. Instruction comes from a list. Teaching requires an interplay between what the student needs, how they are being directed, and in what way(s) that direction is or is not being manifest in their doing.
In order to convey yoga I must be very careful to be myself in class, be authentic, AND not get carried away with what I will call “the show”. So I work diligently to keep my ego out of the mix. It is only a bland person that is a bland teacher. When I am passionate about the practice, when I am practicing what I teach (or living the yoga) then that integrity is transmitted to the student - no matter what I do or do not rub in their temples, place on their mat, whisper across the room, or chat to close. Students feel what the teacher radiates from inside.
Along with this I maintain a perspective that I am merely a conduit through which yoga passes and that the class is not “my” class but rather “their” class. As such, while expressing my passion for the practice (which comes from the depths of my own practice) I try to deliver in such a way that I am economical with words AND that those words are actually ones that serve the student - rather than my own need to be seen, heard, liked, or acknowledged.
That having been said, I do use humor, analogy, quotes, and light in my teaching. I open class with the gayatri mantra (as do my peers) since this is the mother mantra of yoga itself, and we always use the meditation techniques of centering the mental and pelvic forces and cocooning to cleanse the aura, both before and after most classes.
