Many People receive inspiration from a dream As for 2 six grade educations.... well the roots of Isshin ryu are heavily entrenched in Gojo-ryu/Shorin ryu... it is not 100% of each... 100% education in one makes you stronger in one 50/50 education in each opens up your mind... and always leaves room for learning.... Simplifiyng the system is a good part of Isshin Ryu Karate.... Not sure what being more advanced system has to do with the actual system, Isshin Ryu is not gojo ryu...its straight infightting, quick snapping techniques (yes we even circluar block)are effective, and it willingness to be adaptable to other styles make it effective. and these are the people that continue to support and grow Isshinryu. I have not seen the differences of Sanchin kata from Isshin ryu to Gojo Ryu... We use it as a kata to develop inner strength and Breathing... what do you feel is missing from the isshinryu kata to not achive that goal?
