The spirit of yoga, the playfulness and the spirit of being willing to experiment and just go for it, is especially vital right now. A lot of yoga is about "core". I got a bit weary and wary of hearing my instructors emphasize core. However it does matter! On both fronts because our physical structure, as we develop it - is akin to our inner core of mind soul and spirit. Let's hear it for personal development and all of our teachers who demonstrate not only poses but also positive mental attitude and just plain grit ..
