Maybe it's time to focus on a non-asana practice?

Yesterday I attended an Inversion Workshop given by Kate Greer, from Sonic Yoga in New York, it was a fairly shoulder and resolve tiring workshop for me, and although I did learn a few good pointers, I overall felt really inadequate. I realize that yoga is without goals, but its nearly impossible for most (all?) of us NOT to at least aspire (better word for goal-setting!) to be better at the fun stuff in yoga, and by fun stuff, I mean inversions. Sure, I've got headstand down, and sometimes even handstand if I can kick up, but this woman opened up a pandora's box for me of all kinds of "floating" through action. What it boils down to for me is that I need to spend some serious time focusing on moola (mula) bandha, as in maybe just do a practice of just sitting with mula bandha engaged, because for me keeping it engaged through my practice hasn't come.

Also, I wrenched my piriformis somehow and have been experiencing some serious low back and hip pain, that oddly enough become dormant during the workshop, but is in full force today, so no practice, no gym, just rest. And well, it's almost as if the universe is like, "Lauren, work on your damn moola bandha for few days (or hell, a lifetime)", so I'll listen. It is after all, the universe talking.
