Not even a yoga mat is needed to do sun salutations. A green grass and the imagination that it’s possible is enough. The grass was soft and fresh. My heels were green after the tiny practice. I can wash them. If I hadn’t practiced on the grass I would have missed a practice. Ideal conditions seldom exist. But one can make the best out out of any situation. Tomorrow my body is so much better prepared for the asanas than without this tiny practice. Just doing it, is it.
