Baddha konasana (titaliasana) Butterfly position
From sitting position with both the legs outstretched forward, bend your knees and press the soles of your feet together. The feet are grasped. The knees move down towards the ground, and with practice reach there; the body is erect and the gaze in front. The asana is held before coming back to the starting position. The thighs are stretched with care. When used for meditation, the hands are placed in Anjali mudra (prayer position) in front of the chest.
The pose strongly opens hip and groin and is one of the few yoga asanas that can be practiced comfortably soon after eating, except for the forward-bending variation with the head on the floor. It is claimed in Light on Yoga, citing Grantly Dick Reed's Childbirth Without Fear, that the pose is beneficial to pregnant women, as regular practice reduces pain during delivery.
