Just yesterday, I watched online an Ashtanga Primary Series class with full vinyasas between poses and half vinyasas between right and left sides of a pose. A full vinyasa in the context of Ashtanga yoga is Sun Salutation A. A half vinyasa, a.k.a THE vinyasa in popular yoga jargon, is the transition as such: (plank)-chaturanga-urdva mukha savanasana-adho mukha savanasana.
This class lasted for two hours and everybody was really really tired at the end. In the normal practice, when we are not as ambitious, we do half vinyasas between poses and between sides of each pose.
I’ve long thought about the role of the teacher or lecturer in psychology. That is no longer a part of my life so my thought have been diverted towards thinking about the role of the yoga teacher. As someone who started practicing yoga at home on her own and struggled to learn from books, I think I can attest for the need for an instructor when it comes to yoga. As much as it is a personal practice, yoga practitioner needs (at least) a second set of eyes to watch her journey closely. One practical reason for this is that it is very easy to do the asanas in a way that can result in short or long term injuries. The other reason is that like in any other learning process, one can lose her motivation and give up even due to the smallest of failures or simply due to laziness.
