शिवरूपस्ततो ऽस्माभिः शिवलोके स मोदते एतद्देवव्रतं नाम महापातकनाशनम् //
śivarūpastato 'smābhiḥ śivaloke sa modate etaddevavrataṃ nāma mahāpātakanāśanam //
Después, por esta observancia, asumiendo la forma de Śiva, se regocija en el mundo de Śiva. Esto se llama Devavrata, el voto que destruye incluso los pecados más grandes.
This verse does not address pralaya; it focuses on the fruit (phala) of a vow—attaining Śivaloka and the destruction of great sins.
It frames vrata as a dharmic discipline and a form of atonement (prayāścitta): a king or householder who has incurred grave faults is taught a sanctioned observance that purifies and restores religious merit.
The ritual significance is the Devavrata itself: it is presented as a powerful observance whose stated result is purification from mahāpātakas and the attainment of Śiva’s realm; no Vāstu or temple-building rule is mentioned in this specific verse.
