Two quick thoughts about Savasana (Relaxation Pose):

  1. If you are guiding your students into a Savasana, be sure to sit in one place.  It is much harder for students to deeply relax if the speaker is moving all around the room.
  2. If you are walking around the room, making adjustments, changing the music, etc., be sure to walk as far away from your students as possible and walk by their feet rather than their heads.  Even when they are deeply relaxed, there is a sense of movement they can feel and having someone walk by your head will make them nervous.
