Matsya Purana — Kailasa
तत्रेष्ट्वा क्रतुभिः सिद्धः शक्रः सुरगणैः सह दिव्यश्छायापथस् तत्र नक्षत्राणां तु मण्डलम् //
tatreṣṭvā kratubhiḥ siddhaḥ śakraḥ suragaṇaiḥ saha divyaśchāyāpathas tatra nakṣatrāṇāṃ tu maṇḍalam //
There, having performed sacrifices (kratus) and attained accomplishment, Śakra (Indra) is established together with the hosts of gods. There is the divine Chāyāpatha, the celestial “path of shadow,” and there indeed is the Nakṣatra-maṇḍala, the circular array of the constellations.
This verse is not describing Pralaya directly; it maps the ordered celestial realm—Indra’s accomplished station and the divine celestial tracks—implying a structured cosmos rather than dissolution.
By highlighting Indra’s ‘siddhi’ through kratu (sacrifice), it reinforces the Purāṇic ideal that righteous ritual performance and dharmic action sustain cosmic order—an ethical model for kings and householders who uphold yajña, charity, and prescribed duties.
Ritually, it emphasizes kratu (Vedic sacrificial performance) as a means to attain siddhi and divine status; architecturally, the term maṇḍala supports the broader Purāṇic/Vāstu idea of sacred circular/cosmic diagrams used in altar layout and temple planning (mandala-based orientation to celestial order).
