The king's son had to set out and complete his adventurous journey, full of knowledge, through the nine kingdoms of the cosmic world; otherwise how should he know which fruits are actually produced by which kind of rule?

“With this journey the father just wanted to give to the son an impression of the manifold possibilities which the world offers - a more precise insight and power of his own over the different cosmic worlds the father wanted to give to the son only much later: on the Island of Overflowing Wealth he once should learn as the ruler of the mermen to locate the fullness of life.

“Then he should practise here, on the Island of Happiness, how to gain all the riches of the nine cosmic worlds completely effortlessly, and on the Island of Wisdom his son should once become so rich that all the riches of all the worlds would not mean anything to him anymore.
