To make

a rough classification of the different schools, which are too numerous to treat in detail, we may distinguish two main categories. These are the 'shorei' and the 'shorinji'. Schools of the former category chiefly emphasise power through severe muscular exercise while those of the later have as their chief aim lightning fast movement. The katas associated with
'Shorei' karate are therefore 'tekki', 'jutte' and 'hangetsu' while 'bassai', 'kanku' and 'eubi' belong to the 'Shorinji' schools. The 'heian' katas (see the chapters on kata) are basic and have movements common to both kinds of karate.
