I have been working for the last two years in this mode...work with my teacher for a short, but intense period of time and then self practice. Long trips to India have also helped along the way, but it is a style that works for me. The excitement that fuels the practice on the first Mysore practice is wild. My plan was to go easy on myself and complete a full clean primary and build from there. Instead I completed primary and continued on to complete all of what I have been taught of second, all the way up to and including a pretty nice Karandavasana.....that's one long practice!
Who knows what day two will have in store, that wild energy it has been my experience, only last one practice.
