"Five years ago I did think I would find that single yoga tradition. But yoga constantly transformed and developed over time. Although there are a couple of main goals, there's nothing that shows up in every single yoga path.

For some traditions it was heightened consciousness and an end to suffering, a way to get out of the cycle of birth, death and re-birth that is so painful. But for other yoga traditions some of the goals were things like supernatural powers and the ability to control other people."
