[QUOTE=FlexPenguin;18615]Most of the yoga practiced today in studios around the world were developed over the last 50 - 70 years. Modern Ashtanga, Iyengar, and Bikram coming especially to mind. They made yoga what they wanted it to be, so are they included?
I am still unsure what is meant by traditional yoga. I do hear a lot about what yoga is ‘supposed’ to be. From what I have learned, it is a personal journey unrelated to what the other guy is doing.

I’m more familiar with Iyengar than the others, and I know that BKS Iyengar practiced all of the classic asanas that have come down to us over a long period of time.
I’m kind of speaking off the top of my head here. Probably classical yoga is a better term than traditional yoga, because there is more than one tradition in yoga. Iyengar, Bikram, and Ashtanga can probably be considered modern traditions. I don’t know about Ashtanga, but Bikram and Iyengar traditions started from a master teacher, and that is probably a good definition of a tradition or lineage in yoga.
Even some of the classical texts are associated with a master teacher (Patanjali, Kapila), although when you get into some of the practices taught in the Upanishads, the teachers are in many cases anonymous.
I think my point is that, traditionally, a yoga organization has been associated with a master teacher and practitioner.
