Tadasana, Samasti, or Mountain Pose is an asana called Tadasana in Sanskrit, tada - mountain, asana - posture; Pronounced as - tah-DAHS-anna. This asana is the basis or foundation of all asanas to follow or from which most other standing postures emerge. Standing poses require the lower limbs to be invoked and controlled at all times to avoid injury or hyperextension (of the knee joint), while adequately switching other muscle groups.
