hi there! i was also put off by Sivananda yoga TTC prices and the size of classes and had booked a place at Yogapoint in Nasik. However, having just come back from a “yoga vacation” at Sivananda ashram i feel i need look no further for my teaching and cancelled Yogapoint TTC!!! the teachers are superb at Sivananda and the style is wonderful. AS for the price i think it is actually value for money and it is internationally recognised and very comprehensive. Yogapoint was less than half price but i dont know how recognised that would be even within India its not very well known.
As for Sivananda class sizes, they are only huge at Neyyar Dam near Trivandrum, and you can book a place at Madurai where classes are about 80 people or UttarKashi where they are 30 people only. you would wait about 9 months for a place at UttarKashi but i have just booked at Madurai succesfully for Feb 2010. If you are able to i would recommend doing a yoga vacation at sivananda ashram before deciding. Sivananda is the only place with the vacation option so most other ashrams you really dont know what you are getting until you arrive as they dont allow stays other than for courses.
Aside from Yogapoint and Sivananda there is a 4 month Yoga Diploma Course each year from oct-jan at Bihar School of Yoga. this is not TTC but it will give you a qualification. it is about 1200 pounds for the four months so very reasonable, or there is the TTC option there, again for a month and im sure it is cheaper than Sivananda. These are the three places that i have heard to be the best for classical yoga. :lol: Personally i have fallen in love with Sivananda style yoga and think it is worth every penny!
