A couple weeks back, I ran into someone who attended my class regularly in the past but discontinued coming after moving to a new apartment. She told me how much she missed the practice we were doing, that she still goes to yoga classes but they are not the same. She felt compelled to admit to me that there is often injurious things happening in these classes and she has sometimes hurt herself inadvertently. She quickly added, "...but I really like the challenge." The statement struck me because it implied that a simple and more deliberate practice is somehow not a challenge. Actually, being consistently careful and attentive with my breath and body is no small task.
