'SUHARI' is an old important martial arts word in Japan.
SU indicates that a beginner must correctly copy all karate techniques from his instructor.
HA means that after a number of years of training, when the karateka has attained a high degree black belt, he is allowed to develop new techniques provided they are improvements. This applies to all movements with the exception of basic techniques.
RI is the highest form. It means that after an even longer period of training than for HA, the Karateka must be able to perform all forms of karate automatically, not stopping to think about his moves.
