Diving in the texts of meditation, I discovered that the kneeling posture is as powerful (if not even more) and effective as the cross-legged that we are all used to see. The name of the kneeling position is called in Sanskrit “Vajrāsana” the Thunder posture. A simple Google search will convince anyone about its amazing benefits. In this pose, I had no back pain. My back was naturally straight without any effort. No pain in the knees also. However, after 10 minutes, the weight of my body made my ankles numb and I had discomfort.
I started experimenting with various cushions, yoga bricks and any prop I could think of. None was good for more than 20 minutes.
