The wholeness of the world is nothing else, but the combination of the dual pairs: man and woman, earth and water, intellect and emotion, materialism and art... 

The man with erect penis embodies strength, power, struggle, fertility, while the symbol of the hippopotamus refers to the creation,
the maternal protection and healing, the ability to experience emotions and the spiritual, artistic energies. 

The two figures, linked together in their independence, are able to represent wholeness, their behaviour and posture symbolising the unity of the body - mind - spirit.
