SuHaRi is a Japanese martial arts term (Aikido, Karate, Judo) and describes the stages of learning to mastery (if there is).
If give here an ultra-short and rough idea of what it could mean, most probably somewhat incorrect and incomplete, still better than nothing:
"Shu Ha Ri is not a linear progression. It is more akin to concentric circles, so that there is Shu within Ha and both Shu and Ha within Ri. Thus, the fundamentals remain constant; only the application of them and the subtleties of their execution change as the student progresses and his or her own personality begins to flavor the techniques performed."[1]
I invite JohnF to write something sensible here about ShuHaRi with regard to Go.
