Utkatasana is known in English as chair pose, but it is a challenging standing posture that builds strength in the lower body.
Utkata konasana is a wide-legged squat where the arms are raised to
shoulder height. The fierce meaning of utakata in this context refers to
the power and fiery strength it builds, and the fierce angle between
the legs and the ground.
Fierce postures such as utkatasana and utkata konasana cultivate both physical and mental power. They create heat in the body and encourage stability and grounding. As well as helping to strengthen the muscles, these fierce standing postures can help the yogi find the inner power to overcome obstacles.
