This is called
Mountain Yoga Pose because it promotes the experience of stillness, strength, relaxed power, and immovable stability associated with mountains. Remember that experiencing yourself in stillness is the most direct way to experience yourself with clarity. This yoga posture, and coming back to this stillness after other poses, is one of the very best ways of becoming acquainted with stillness.
Mountain Yoga Pose (Tadasana)
Tadasana is the most basic pose and is, therefore, the foundation for all others. Being stationary and passive, involves learning to stand erect, relaxed, and still. The position has two primary lines of energy radiating outward from your center: one line moving upward through the spine and one line downward through the legs. Your hips will be in cat tilt.
