When sadness takes over the mind, we should look for the rainbow within our heart to lead us back to our calm place. Meditation and finding your inner calm are the themes of Fluffy and the Rainbow in his Heart— book two of an endearing children’s picture book series by Tools of the Heart. Mother Earth and Father Sun (from book one of the Tools of the Heart book series) begin to worry when parts of their precious garden become sad. Father Sun makes it his mission to investigate the problem and finds a very sad little squirrel named Fluffy. With love in his heart, Father Sun helps to comfort Fluffy, and teaches him about the rainbow of wisdom in his heart– and how to replace the dark clouds with joy.
