Shiva Purana
उत्पादकत्वाद्रजसोतिरेकाल्लोकस्य संतानविवृद्धिहेतून् ॥ अष्टौ विकारानपि चादिकाले सृष्ट्वा समश्नाति तथांतकाले ॥ ४७ ॥
When the Rajas predominates it becomes generative. It creates the eight secondary tattvas in the beginning, which cause flourishing of the worlds. In the end it devours them.
