विष्णूत्पत्तिवर्णनम्
Description of the Origin/Manifestation of Viṣṇu
इत्थं सत्यंधतमसे सूचीभेद्यं निरंतरे । तत्सद्ब्रह्मेति यच्छ्रुत्वा सदेकं प्रतिपद्यते
itthaṃ satyaṃdhatamase sūcībhedyaṃ niraṃtare | tatsadbrahmeti yacchrutvā sadekaṃ pratipadyate
Thus, in the midst of dense darkness, when the continuous veil is pierced as though by the tip of a needle, and one hears (realizes) “That is Sat—Brahman,” one comes to abide in the One Existent Reality.

It teaches that liberation begins when the unbroken darkness of ignorance is “pierced,” and the seeker recognizes the Supreme as Sat (the Real). This recognition stabilizes the mind in the One Reality, a core Shaiva goal leading toward moksha.
In Shaiva practice, Saguna worship (such as Linga worship) purifies and focuses the devotee so the inner veil of tamas can be pierced. The verse points beyond forms to the realized truth—Shiva as the One Sat—while not rejecting devotional means.
A practical takeaway is steady śravaṇa–manana (hearing and contemplation of Shiva-tattva) supported by japa of the Panchakshara (Om Namaḥ Śivāya) to cut through tamas and abide in the One Reality.
