Can an Ashtanga yoga practice be soft, even relaxing from the beginning on? It can.
It is possible to do only a few surya namaskara As.
It is possible to practice slowly with breaks, if necessary.
It is possible to omit asanas.
It is possible to omit vinyasas between the sides.
Doing this it can be a relaxing practice. Ha, I consider already to practice. Soft, very soft, I want to move my body...........
