"This happens in yoga classes, too. Students come to class week after week. They watch the teacher. They watch the other students. Much of their experience is essentially external. Even though their bodies are doing the poses, their minds are directed toward outside stimulation, comparisons with their classmates, the approval of the teacher.
I’m not saying they are bad students or that they are wasting their time. Of course, part of the reason we go to class is to take in information, to be guided toward an experience of something pleasurable or uplifting or challenging, to be inspired by our teachers. But at some point, for us to really touch the heart of yoga, these experiences must be internalized. And the only way to do that is to practice on our own."
