The name comes from the Sanskrit words matsya (मत्स्य) meaning "fish" and asana (आसन) meaning "posture" or "seat".. The asana is a backbend, where the practitioner lies on his or her back and lifts the heart (anahata) chakra by rising up on the elbows and drawing the shoulders back. 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. This should not be done if you are pregnant. Likewise, if you suffer from serious lower back or neck injury, it is better to avoid this asana.
