What is the proper before-class ritual?
Basically this involves the students kneeling in one or more lines parallel to the front of the dojo, or shomen. The sensei enters and kneels. All present bow toward the shomen (where a picture of O Sensei [or a piece of calligraphy representing the kanji for “ki” in the case of Ki Society Aikido] is traditionally on display). Then a further bow, sensei to class and class to sensei. There may or may not be clapping or words uttered.
