I agree completely with the author of this piece. As a teacher of Viniyoga, I am ashamed that there has also been a scandal in our lineage, although not mine directly. I won't publish details here, but it is easy enough to dig up. Notably, the person involved is back teaching, without apparently having to atone for his indiscretions. For me, his alleged bad behaviour does not detract from the essence of the teachings of his father, TKV Desikachar and grandfather, T. Krishnamacharya. However, I do believe that the organization that promotes the teachings of Viniyoga ought to be strong enough to discipline even the direct descendent of its founder. Anyway, here is the link.
