Matsya Purana — Catalogue of the Eighteen Puranas
स्कान्दं नाम पुराणं च ह्य् एकाशीतिर्निगद्यते सहस्राणि शतं चैकम् इति मर्त्येषु गद्यते //
skāndaṃ nāma purāṇaṃ ca hy ekāśītirnigadyate sahasrāṇi śataṃ caikam iti martyeṣu gadyate //
As for the Purāṇa called the Skanda (Skānda), it is declared to contain eighty-one thousand and one hundred verses—so it is said among mortals.
This verse does not describe Pralaya; it functions as a catalog entry, giving the traditional verse-count (extent) of the Skanda Purāṇa within the Matsya Purāṇa’s enumeration of scriptures.
Indirectly, it supports dharma by pointing to the recognized Purāṇic sources a king or householder might consult for ritual, tīrtha, vrata, and ethical guidance—here emphasizing the Skanda Purāṇa’s authoritative breadth.
No specific Vāstu or temple rule is stated in this verse; its practical significance is bibliographic—identifying the Skanda Purāṇa as a large compendium often associated with tīrtha-māhātmya and ritual observances.
