1) If a kata is just a grouping of selected self-defense techniques used to highlight a specific concept why does that kata have to flow or have a rhythm?
2) If a kata is a microcosm of a whole system can it possibly hold counters or defenses for every attack and “teach” all techniques of said system? Or does it revert back to just the concepts of a particular master who created it. Example; A kata has a bunkai for a wrist lock but no technique for defending a choke. But then it may be that the creator wanted to show his use of leverage and made said kata. He has only shown one principle of his style? He would have to create a kata for each concept?
3) If kata were created because of the above view points, How many of those original kata does one need and at what point did the other hundreds of kata created have nothing to do with “hidden techniques of a system, fighting ranges or concepts. Any kata invented by anyone after WW2 would be superficial correct? Any kata created after say 1800? would be just “another kata’? Any kata not created on Okinawa would be a modern kata that merely overlaps an original? If “X” kata teaches close in and turning would that kata just be extra since one of the original ones handed down from China already address that concept? Is this why some do only 6 or 8 kata?
