After the physical death the life that cannot die bears man up and he remains always alive. Both on earth and on the sea we living beings exist, having both elements in our form, the earth and the water. The beings of the sea are formed of earth as well; we have water also in our constitution. Yet the sea is as strange to us as the earth is to the creatures of the sea. Neither would like their place exchanged; and if it so happens that they are out of their element, it leads them to their end. It is because the fish has not realized that it is also an earthly being and that the earth is its element too, that it cannot live on earth; and in the same way beings on land whose life depends on getting to the shore, fail when they believe that they will sink in the sea.
