“Thus we use improvisation to bring something new and useful into the practice of Āsana.
Therefore, if one of you is asked to do an Āsana with the legs straight and another to do that same Āsana with the legs bent, please don’t think you are winning or losing a contest.
Since this is not dance, form is not important.
What is important when doing an Āsana is the experience that happens at the moment.”
