Matsya said:—That High Soul living in water began to practise asceticism there. Since then, the species of aquatic animals began to appear. Then that highly powerful Soul wanted to create worlds and thought of the universe that is made up of five elements. In course of that conception, that ocean, void of air and space, became disturbed and by that disturbance the womb of the subtle universe was created, which being again agitated, begot small subtle holes and sound and it gave birth to air which found space and thus expanded.—1-5
