From Day 88 of Rolf Gates and Katrina Kenison's Meditations from the Mat:

When we do feel lost or uncertain, drifting away from our practice, blocked from our own truth, it helps to remember that darkness and confusion, too, are part of the path. The hero's journey is a journey inward. Yoga is not a workout, it is a work in. In the Tao Te Ching, we read that the only real movement is return. And this is the point of spiritual practice: to make us teachable, to open our hearts and focus our awareness so that we can know what we already know, and be who we already are.
