Placing the right foot at the root of the left thigh, encircling the (right) knee by the left leg, holding (the two feet by the opposite hands), twisting the body and staying in this posture is the Asana. Matsyendranath was the legendary teacher of yoga. The twist based on his name energizes the spine and stimulates the digestive fire. Traditional texts say that Ardha Matsyendrasana increases appetite, destroys most deadly diseases, and awakens Kundalini.

"Having placed with the right foot at the root of the left thigh, let the toe be grasped with the right hand passing over the back, and having placed the left foot on the right thigh at its root, let it be grasped with the left hand passing behind the back. This is the asana, as explained by Sri Matsyanatha. It increases appetite and is an instrument for destroying the group of the most deadly diseases. Its practice awakens the Kundalini, stops the nectar shedding from the moon in people." Swartmarama, says, in the Hatha Yoga Pradipika.

For the beginners this Asana is made easy and named Ardha-Matsyendrasana. The only difference is that in Matsyendrasana the folded leg is placed at the root of the thigh below abdomen, in Ardha-Matsyendrasana it is placed by the side of the opposite buttock.

Beginner`s Tip: In this version of the pose, the opposite-side arm is wrapped around the outside of the raised-leg upper thigh. This may be impractical, and potentially harmful, for beginning students. Be sure to sit up well on a blanket support and for the time being just wrap your arm around the raised leg and hug the thigh to your torso.
