Shavasana - Wikipedia, the free encyclopedia

Shavasana is perhaps the most important part of yoga practice. Lying on the back, the arms and legs are spread at about 45 degrees, the eyes are closed and the breath deep, using deerkha (long) pranayama. The whole body is relaxed onto the floor with an awareness of the chest and abdomen rising and falling with each breath. All parts of the body are scanned for muscular tension of any kind, which is consciously released as it is found, optionally with a small repetitive movement of the area. All control of the breath, the mind, and the body is then released for the duration of the asana, typically 20–30 minutes although often less in Western yoga classes.
The asana is released by slowly deepening the breath, flexing the fingers and toes, reaching the arms above the head, stretching the whole body, exhaling, bringing the knees to the chest and rolling over to the side in a fetal position. After a short time and a slow inhalation, the practitioner takes a seated position.
