The river is a metaphor for life. "Follow your heart to the water", or, do what you think is right for your life. Follow your heart through life. But then he stipulates this by saying, "Fill your pockets with stone" so as to say, sink to the bottom of the river, or in other words, stay where you are in life. Don't move along down the river/through life and leave me. "Throw your arms around me, never let me go".
In short, it's just about being left by someone you love.
