Matsyasana

Matsyasana (Sanskrit: मत्स्यासन; IAST: Matsyāsana) or Fish pose[1] is a reclining back-bending asana in hatha yoga and modern yoga as exercise.

It is commonly considered a counterasana to Sarvangasana, or shoulder stand, specifically within the context of the Ashtanga Vinyasa Yoga Primary Series.

The neck is lengthened, and the crown of the head Sahasrara chakra is "pointed" toward the 'wall' behind the practitioner.

As the arch of the back deepens with practice, and the heart and throat open further, the top of the head may brush the ground, but no weight should rest upon it.

The pose can be supported with a bolster under the back, and with a cushion under the knees.
