It's somewhat embarrassing, but sometimes when my work is featured in print, or occasionally on tv, or radio, people refer to me as "The Harmonica Guru."

Of course, calling someone "The _______ Guru" can simply mean that they are considered expert in their field.
For example, there used to be a fellow up here in Vermont that some people called "The Riding Mower Guru." If you had a riding lawn mower, old or new, in good shape or not, he'd keep it going. Since I've taught more than a million people to play harmonica, and written a dozen books on the subject, I suppose it's not surprising that some people use the HG term.

But, I also teach mindfulness and meditation. And I do it through the harmonica. Quite literally.
Which is why some people use the HG phrase.
Though I'd never call or consider myself a guru, thank you very much!
That's just asking for trouble. And I've said, regarding Bhakti Yoga (the Yoga of Devotion) that I'm just not into devotional practices — either giving, or getting!

A big part of trying to be mindful is not to get too attached to what other people think of you.
Or what you think of yourself.
Or of thought in general.
So the act of "being someone special doing something special" is in many ways detrimental to being mindful.

On the other hand, I need to make a living doing what I think is important (teaching mindfulness, often through the harmonica).
And people like a simple, no-brainer way of describing or remembering someone.

So like anything else, self-promotion vs. reducing emphasis on the self is a fine balancing act...
Just a thought...
