This asana is difficult to perform. This asana presses the Kanda (the place near the navel). So it is called Kandapeedanasana.
Technique : Sit on the floor. Bend the legs at the knees. Bring the feet towards the trunk until the heels are close to the perineum, and keep the knees on the floor. Join the palms in front of the chest. Keep the trunk erect. Keep the nose, the palms and the feet in a vertical straight line. Breathe in the normal way. This asana should be practised with caution. Persons whose thighs and calves are heavy will find it difficult to practise this asana. Those having a slim body can perform this asana comfortably.
