Wonder if Sharath practices it...don't suppose anyone is brave enough to ask him about it.
SLOW ASHTANGA : Pattabhi Jois talked in interviews, as well as when writing in Yoga Mala, that if we had less time we should practice less asana. In my own practice time is an issue. I prefer to breathe more slowly in the asana and vinyasas, lengthening my inhalation and exhalation, "slow like the pouring of oil" as Krishnamacharya puts it in Yoga Makaranda. I like to explore kumbhaka and the occasional extended stay, in Mudras especially. I also prefer to practice, much of the time, with my eyes closed, employing internal drishti at different vital focal points and I like to introduce vinyasas, extra preparatory asana on days when they feel appropriate as well as perhaps extending an asana into more challenging, 'proficient' forms on the more flexible days, in keeping perhaps with Krishnamacharya's, Primary, Middle and proficient groups of asana rather than Pattabhi Jois' fixed sequences. I like to practice Pranayama before and after my asana practice as well as finishing my practice with a 'meditative activity'. I was first introduced to Yoga through the Ashtanga sequences and I still maintain that general structure in my main practice but I would rather sacrifice half or more than half a sequence than these other factors and perhaps practice the asana ‘missed’ in the following days, I still consider this to be Ashtanga, Slow Ashtanga.
