Matsya Purana — Manvantaras
परिणाहोच्छ्रये तुल्या जायन्ते ह कृते युगे षण्णवत्यङ्गुलोत्सेधो ह्य् अष्टानां देवयोनिनाम् //
pariṇāhocchraye tulyā jāyante ha kṛte yuge ṣaṇṇavatyaṅgulotsedho hy aṣṭānāṃ devayoninām //
In the Kṛta Yuga, they are said to be equal in girth and in height; and the canonical height for the eight divine types (deva-yonis) is ninety-six aṅgulas.
This verse does not discuss Pralaya; it preserves iconographic standards—how divine forms should be proportioned—framed as an authoritative rule associated with the Kṛta Yuga.
By supporting correct temple building and image-making, a king or householder upholds dharma through patronage of properly measured consecrated images, ensuring ritual efficacy and social-religious order.
It gives a key pratima-lakṣaṇa rule: divine images (eight deva-yoni categories) should follow a fixed iconometric height of 96 aṅgulas with proportional equality of girth and height—guiding sculptors, architects, and consecration rites.
