"You can never step into the same river twice...." --- T.K.V. Desikachar
The Ashtanga Apprenticeship Program is not a "Yoga Teacher Training", "YTT", "200 Hours", or Authorization/Certification in Ashtanga Yoga.
To receive Authorization or Certification to teach Ashtanga Yoga (as taught by Sri. K Pattabhi Jois), it is done through extensive study under the tutelage of the lineage holders of this method: currently, Sharath Jois (SYC) and Saraswati Jois (KPJAYI). Both the SYC and KPJAYI are based in Mysore, India and are the only yoga Shalas permitted to designate the authorization or certification to teach Ashtanga Yoga.
