Lie down or stand, close your eyes, connect to your breath. 

Give your breath time to sit in and with you body.  

When you feel you are whole with you breath, 

Begin to feel and see yourself as a jellyfish.  

Allow the breath to move you a Jellyfish, raising and falling, full of water in the water.  

If you want, to put on some music, use Ashra Baladi music or music that is slow and fluid and allows your breath and body to respond.  Let me know what happens.
