(THE FISH POSE)
This pose is called Matsyasana because by assuming this posture and doing Plavini Pranayama you can float like the fish on water as long as you like.
Spread a thick blanket on the ground. Sit on it with legs fully stretched in front of you. Do Padmasana. Then lie flat on the back. Then resting the whole body on the elbows raise the trunk and head. Pressing the head well on the ground on the one side and the buttocks on the other, make an arch or a bridge of the trunk. Rest the hands on the thighs or catch hold of the toes the right hand holding the left toe and the left hand the right toe.
Practise this Asana soon after Sarvangasana for one third of the time you devote to the latter, if you want the maximum benefits. Sarvangasana and Matsyasana go hand in hand. They must always be practiced one after the other. When you have finished doing this Asana, slowly release the head with the help of the hands, sit erect and unlock the foot-lock.
Matsyasana gives a soothing massage to the neck and the shoulders. The stiffness of the neck is removed. Matsyasana helps deep breathing.
