Sit in Mukta-Padmasana or any asana of your convenience and lie down. Keep both knees parallel to the floor in Padmasana. Lift the voice and face upwards and bend the neck backwards as much as possible. Keep the vocal cords intact. The brahmatalu should touch the ground, not the back of the head. As the neck bends backward, the abdomen and thorax rise up and the entire spine becomes arched. Thus extending the hands in front, hold the thumb of the right hand with the left hand and the thumb of the left hand with the right hand. First practice the asana for half a minute or a minute. When for three minutes it is no longer difficult to remain firmly established in the asana, then the asana will be considered well established.

Mukta Padmasanam Kirtba Uttalshayananchret.

Kupravhang Shiroveshtya Matsyasanast Rogha.

(Herald-Samhita - 2/11)

Yogis are bound in this asana from time to time and float like fish on water with Kumbhaka. That is why it is called Matsyasana.

Practice this asana for a minimum of two minutes, a maximum of five minutes. Those who have difficulty in raising their chest due to excess fat in the body, should place a pillow on the surface, then there will be no difficulty in being established in this seat.
