In the spiritual world there is placed called The Water Park which is described in the book The Astral City. There exists exquisite beauty. The woods are in bloom and the fresh air was filled with a gentle aroma. It is a miracle of colours and lights. A great river wound its way leisurely between green banks sprinkled with blue flowers. The slow-moving waters, shimmering in the sun, reflected, like a crystal mirror, the many shades of blue in the sky. Wide paths cut through the woods in different directions, and at regular intervals large trees spread their friendly branches offering areas of shade in the sun-bathed landscape. This is the Colony's great reservoir.

         The waters of the Blue River are drawn into huge compartments from which they are distributed to every district in the Colony. There, water is used especially for nutritive and medicinal purposes. The water there is much lighter and purer, almost fluidical.

         The habitants of the colony recognize the value of this divine and precious gift and thank God for it. When the book was launched in 1944, the Astral City had one million habitants.
