Imagine that the stress from your worries and problems is flowing away, out of your body, down, down, down the drain. The energy and tension that you are holding in your body (shoulders, neck, back, head, legs, arms, stomach) from these worries can be released into the flowing water. Let the warm, pulsing beat of the stream untie the physical knots. Take deep cleansing breaths as your cares float away.
The idea is to release the tension that results from emotional stress, so that you can manage your concerns and problems more effectively.
