With respect to my dojo: the IS stuff is infused in everything we do. Gleason sensei teaches an internals class once a week and then vibes off the material from that class in his normal aikido classes. In addition, he often elaborates in terms of the kotodama as they relate to aiki and aikido. Its great
You get feedback on this stuff every week in your home dojo, while I have to wait for seminars coming my way. I envy you!
