I like your preliminary crane pose. I was looking at a picture of Vishnudevanda doing it with his foot behind his head looking perfectly balanced. He didn't have the preliminaries in the "complete" illustrated book of yoga.
I think the next stage past the illustration you attached Teo, is the form where you lift your heel as far into your groin as you can with your toes pointing down toward your knee joint and then you bring your palms together and either balance with hands in prayer pose over the Heart Chakra or over your head. You have to center your body over your standing foot, so your hip will be off to the side a bit, and it always helps to spot something about 12 feet away so you stop feeling shaky, which you will be if you started out look at what you are doing with your legs.
Don't forget to do both sides when you do a posture like the crane.
Thanks for yogic jumping pin. The rug is ready and it's a better day for standing on your own head than to let others do it for you 'roun here.
Atlas should stop shrugging so much and keep doing that shoulder stand meditatively.
Namastes and longer days. . . (unless you're down under where they are starting hurricane season and autumn has arrived.
Keep your roving third eyes open!
