Vajrasana (The Adamantine Pose)
Those who sit in this Asana have a quite steady and firm pose. They cannot be easily shaken. The knees are rendered very hard. Merudanda becomes firm and strong. This Asana resembles more or less the Namaz pose in which the Muslims sit for prayer.
Keep the soles of the feet on both sides of the anus, i.e., place the thighs on the legs one over the other and the soles on the buttocks. The calves must touch the thighs. The part from the toe to the knee should touch the ground. The whole burden of the body is put on the knees and ankles. In the beginning of practice you may feel a slight pain in the knee and ankle-joints but it passes off very quickly. Massage the painful parts and two joints with the hands. You can use a little Iodex or Amrutanjan for rubbing. After fixing the feet and the knees, put both the hands straight on the knees. Keep the knees quite close. Sit like this keeping the trunk, neck and head in one straight line. This is the most common Asana. You can sit in this Asana for a very long time comfortably. Yogins generally sit in this Asana.
If you sit in this Asana for fifteen minutes immediately after food, the food will be digested well. Dyspeptics will derive much benefit. The Nadis, nerves and muscles of the legs and thighs are strengthened. Myalgia in the knees, legs, toes and thighs disappears. Sciatica vanishes. Flatulence is removed. Stomach exercises a stimulating, beneficial influence on Kanda, the most vital part from which all the Nadis spring.
