These recordings are designed to help you sleep more deeply and, in time, for the whole night. Please do these on your bed, or on the floor, and not in bed—try to follow the instructions rather than let yourself fall asleep. Paradoxically, staying awake and doing the practise will tangibly improve that night's sleep. The first recording is designed to be done lying; the second is done sitting. If you think you might not be able to stay awake while listening, try the seated version first—it's easier to stay awake while sitting!
Both recording feature Darren Zeising's wonderful compositions of gently shifting tones—these tones are designed specifically to heighten the relaxation effects.
Just a note that this is the lying relaxation not the seated one.
Whoops—looking into this now.
