Yes THANKS - that looks like a great way to liver de-tox. Now to do it regularly.....!!
Re: Yoga being slow. REad once in an excellent yoga book that the slower one does it the intensiver the work-out for deeper lying musculatur. Another imp. aspect that many yoga teachers and students avoid (part of the quicker/modern way of doing yoga ) is the immediate pause after the strenuous part. Ex. 15-30 secs holding a position and then 15-30 secs of letting go and relaxing. Thereby allowing the full circle to benefit the exerciser. Its like breathing in and breathing out. One has to follow the other. Or else it would be like the people who have asthma... who can breath in but not out. I admit it needs time, patience and practising - the letting-go part but its what makes yoga so special. This is the time spent getting to sense ones body (and blockades) "better" - in an intuitive manner.
Namaste!
