The technique in Ashtanga yoga is breathing. Stretching when inhaling, going deeper in a pose when exhaling. It is engaging the muscles, engaging mulha bandha and uddyjana bandha. To relax in a pose is helpful, too. The vinyasas make sure that the body remains hot. A hot body is easier to bend. Repetition helps, daily repetition, but also repetition of a pose in the same session. To experience joy is helpful, too. We learn easier when we like something. These techniques help learning poses of the 6th series and they help a beginner.
Oh, I had a sweaty practice this morning. Kurmasana improved, my shoulders touched the floor today, heels didn't lift up, not a bit, but I feel that I am close to that.
I tried pincha mayurasana and my hands remained where I put them. This was great, too.
The body is prepared now for a second practice in the evening: I'll go to a led class.
