"Most people think that 'guru' refers only to an enlightened being. But a guru can manifest as anyone or any aspect of the universe that offers teachings and empowerment. Adopt the posture of a student. Teachings can appear anywhere at any time; if you look for the Guru in all things, then the Guru constantly manifest to uplift you." --Yoga Journal June 2008
I like this description of what a guru is. I think today I'll try to "adopt the posture of a student," and see what I can learn.
Have a presence-filled day Friday!
