Matsya Purana — Yuga Durations
देवतानां च सर्वासां ब्रह्मादीनां महीपते दैत्यानां दानवानां च यक्षराक्षसपक्षिणाम् //
devatānāṃ ca sarvāsāṃ brahmādīnāṃ mahīpate daityānāṃ dānavānāṃ ca yakṣarākṣasapakṣiṇām //
O king, (this pertains) to all the gods beginning with Brahmā, and also to the Daityas and Dānavas, and to the Yakṣas, Rākṣasas, and the bird-like beings.
This verse does not directly describe Pralaya; it functions as a catalog of cosmic classes of beings, implying an ordered universe in which multiple divine and semi-divine races are acknowledged.
By addressing the king and listing beings across the cosmic spectrum, the verse frames rulership as responsibility within a wider moral-cosmic order—kings are reminded that dharma operates amid many powers, not only human society.
No explicit Vāstu or ritual procedure is stated in this line; its primary significance is cosmological—identifying categories of beings that later ritual texts may invoke, propitiate, or acknowledge.
