caturdaśasu tāvanto jñeyā manvantareṣviha
āsurī yātudhānī ca paiśācī yakṣarākṣasī //

In all the yugas the Asuras, evil spirits, demons, Yakṣas the Piśāchas and the Rākṣasas and various others are born All these persons are endowed with characteristics in accordance with what they had in previous yugas As the characteristics of yugas change, so the characteristics of the several Manvantaras change These worlds of the jīvas are always liable to change, they do not remain constant even for a moment Thus I have described to you the characteristics and changes of the yugas. I will tell you about Manvantaras at the time when I deal with Kalpas—105-108
