I thought: Today I am courageous, today I drop back on my own. My back bending is as deep as it never was. It feels also good, I enjoy it to arch back. But no way to let go, no way to drop back on my own. I need psychological support, means I need my teacher B. to do it.
I practiced 1 hour, only second series till parsva dhanurasana. Loved it.
Urdhva dhanurasana will still keep me busy. It is a challange, no doubt.
