Thou art, Achyuta, the cause of gods, Yakhas, Asuras, Siddhas, serpents, choristers, dancers, goblins, demons, men, beasts, birds, insects, reptiles, plants, and stones, earth, fire, water, sky, wind, sound, touch, taste, colour, flavour, mind, intellect, soul, time, and the properties of nature; and these are all manifestations of thine.

In plain words: Prahlada says Vishnu, called Achyuta (the one who never falls), is the source of everything. That includes gods, demons, people, animals, plants, stones, the elements, the senses, the mind, time and nature. All of these are his forms.
