Tadasana or mountain pose is the foundational standing pose in hatha yoga. The alignment in the posture influences all of the other standing postures so it’s important to work on your alignment to get a sense of how proper posture here influences other poses in your practice.
It may seem odd to teach people to stand correctly but that’s what we do. As you watch the video notice how even my posture changes in the pose. I have a small sway back and it’s interesting to see myself in video form leading you through the alignment. Feel the pose as you make shifts. Your body will tell you what feels right if you listen. As you move or adjust yourself further notice how one part of your body flows into another differently due to the changes you make.
In the pose always continue breathing calmly. Increase, follow and explore the breath. See where it takes you.
