Matsya Purana — The Episode of Madhu and Kaiṭabha: Gunas
तौ तत्र विचरन्तौ स्म पुष्करे विश्वतोमुखम् योगिनां श्रेष्ठमासाद्य दीप्तं ददृशतुस्तदा //
tau tatra vicarantau sma puṣkare viśvatomukham yogināṃ śreṣṭhamāsādya dīptaṃ dadṛśatustadā //
While the two of them were roaming there in Puṣkara, they then approached Viśvatomukha—the foremost among yogins—and beheld him, radiant with spiritual splendor.
This verse does not describe pralaya or cosmology; it focuses on a tirtha setting (Puṣkara) and the vision of a radiant, exemplary yogin, highlighting sanctity and spiritual attainment rather than dissolution.
Indirectly, it supports the Purāṇic ethic that rulers and householders should seek the company and counsel of realized sages; approaching the ‘foremost among yogins’ models humility, pilgrimage, and learning from spiritual authorities.
No explicit Vāstu or temple rule is stated; the ritual takeaway is the importance of tirtha-darśana—pilgrimage and the auspicious sight (darśana) of a spiritually luminous yogin at Puṣkara.
