Dwikonasana (double angle pose) is a posture for awakening anahata chakra, the heart chakra or literally seat of the "unstruck sound". Anahata chakra is the energetic center for the spiritually emotive sensations of love, compassion, connection and understanding. It is also the bridge point between the individualized consciousness with the universal consciousness.
Therapeutically dwikonasana strengthens the intraspinatus muscles and other major muscle groups sarrounding the shoulder blades including the rhomboids, teres muscle, and trapezius muscles. It also tones and develops the chest and neck. This practice should not be performed by those who have shoulder injuries.
