Sava = Corpse , Asana = Pose or Posture

It is a relaxing position practiced at the end of the yoga session where the body is kept still in a supine resting pose, in which you lie on your back, fully relaxed with your arms and legs extended, palms face up by your side, and eyes closed. Those with lower back troubles can practice savasana with a blanket or bolster under their knees, to allow the low back to lie flat. 

We should always save at least 3 to 5 minutes for corpse pose at the end of our asana practice.
