I have discovered a way to sit in bradvajasana I legs (check) on my couch with support. I let my legs have enough compression for effect but enough space to breath. The focus is in the hips. A block under one hip, Princess and the Pea style. After about 5-10 minutes of sitting lifted and periodically doing light turns in the proper direction I could feel my lumbosacral muscles relaxing. Like chocolate melting, fibrous knots of muscle slowly release and descend. During the second set I could feel effects as far up as my neck. Keeping my chest lifted was the hardest part.
I still use music to set my mind at home. It’s about 50-70% effective depending on the music. My attention span is at odds with the flow of time. That’s my work on stillness. It’s the main battle in my war against entropy.
