Adhyaya 71: पुरत्रयवृत्तान्तः—ब्रह्मवरदानम्, मयकृतत्रिपुर-निर्माणम्, विष्णुमाया-धर्मविघ्नः, शिवस्तुति, त्रिपुरदाहोपक्रमः
पुरत्रये तदा जाते सर्वे दैत्या जगत्त्रये पुरत्रयं प्रविश्यैव बभूवुस्ते बलाधिकाः
puratraye tadā jāte sarve daityā jagattraye puratrayaṃ praviśyaiva babhūvuste balādhikāḥ
Ketika Tripura—tiga kota—telah terwujud, semua Daitya di tiga dunia memasuki benteng-benteng rangkap tiga itu; dengan berlindung di dalamnya mereka menjadi sangat perkasa.
Suta Goswami (narrating the Tripura episode to the sages of Naimisharanya)
It frames Tripura as a symbol of fortified bondage (pāśa) in the three worlds; Linga worship points the pashu (soul) to Shiva as Pati, the refuge beyond such constructed strongholds.
By implication, it sets up the contrast: asuric power grows through external refuge in Tripura, while Shiva-tattva is the transcendent Lord (Pati) who alone can dissolve the triple limitation and restore cosmic order.
No explicit ritual is stated; the takeaway aligns with Pashupata Yoga—withdrawal from dependence on worldly ‘fortresses’ (attachments) and taking inner refuge in Shiva through japa, dhyāna, and Linga-upāsanā.
