This Asana is performed in Vajrasana Position. As the belly gets folded in this Asana, there comes tremendous pressure on intestines, liver, spleen, certain glands, etc., and this pressure improves their functioning and removes complaints regarding digestive system & constipation. This Asana is also used to awaken the kundalini shakti, which, however, requires its prolonged practice.
Owing to the placement of the palms at the navel, there is more pressure on the belly. This increased pressure makes the benefits of the earlier Asana more prominent.
