Vajrasana

Those who sit in this Asanas have a steady, firm pose. They can't be easily shaken. The knees are rendered very hard. The Meru Danda becomes firm and strong. This Asanas resembles more or less the Nimaz pose in which the Muslims sit for prayer.

Technique:    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 thjghs. 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. After fixing the feet and the knees, put both the hands straight on the knees. Keep both the knees quite close. Sit straight like a king. Yogis generally sit in this Asana.

Benefits:       If you sit in this Asana for about half an hour immediately after food, the food will be digested well. The nerves and muscles of the legs and thighs are strengthened. Sciatica vanishes. The stomach works vigorously. The practice of Vajrasana exercises a stimulating, beneficial influence on kanda, the most vital part, which is situated 12 inches above the anus and from which 72000 nadis spring.

Bhujangasana.

Bhujangasana means a cobra in Sanskrit. When this pose is exhibited, the raised head and trunk resemble the raised hood of a cobra. Hence this is called bhujangasana.
 
Technique:  spread a blanket on the ground. Lie flat downwards keeping the back above. Relax all the muscles. Be at ease. Place the palms on the ground just below the shoulders and elbows.  Let the body from the navel downwards to the toes touch touch the ground.  Raise the head and upper portion of the body slowly just as the cobra raises its hood.  Bend the spine backwards.  Now the muscles of the back and lumbar regions are well stretched.  The intra-abdominal pressure is also increased.  Then slowly bring down the head to its original position.  When you lie down at first with the face downwards on the ground, the chin is pressed against the chest.  The chin-lock is formed.  Repeat the process of raising the head and bringing it down half a dozen times, steadily. Breathe slowly through the nose. Retain the breathe till you raise the head and bend the spine properly. Then exhaling the breath slowly, bring the head down. As soon as head touches the ground, breathe again slowly.
