Matsya Purana — Account of the Manvantaras: Manus
ऋभवो ऽथ ऋभाद्याश् च वारिमूला दिवौकसः चाक्षुषस्यान्तरे प्रोक्ता देवानां पञ्च योनयः //
ṛbhavo 'tha ṛbhādyāś ca vārimūlā divaukasaḥ cākṣuṣasyāntare proktā devānāṃ pañca yonayaḥ //
In the Cākṣuṣa Manvantara, five yonis (origins/classes) of the gods are declared: the Ṛbhus; the groups beginning with the Ṛbhus; the water-rooted beings; and the heaven-dwellers.
It focuses on creation-era taxonomy rather than dissolution: it classifies divine beings into “five origins” specifically stated for the Cākṣuṣa Manvantara.
Indirectly, it supports Purāṇic dharma by mapping cosmic order (deva classifications) that kings and householders are expected to honor through correct ritual observance and reverence toward celestial hierarchies.
No direct Vāstu rule is stated; the ritual takeaway is cosmological: knowing deva-classes is relevant for correctly addressing deities and celestial groups in offerings and invocations.
