Little human upon the sand From where I'm lying here in your hand, You to me are but a passing breeze. The sun will always shine where you stand Depending in which land You may find yourself. Now you have my blessing, go your way. Happiness runs in a circular motion Thought is like a little boat upon the sea. Everybody is a part of everything anyway, You can have everything if you let yourself be. Happiness runs, happiness runs. Happiness runs, happiness runs. Happiness runs, happiness runs. Happiness runs, happiness runs. .... Why ? Because. Why ? Because. Why ? Because. Why ? Because. Happiness runs in a circular motion Thought is like a little boat upon the sea.
