Matsya Purana — Prayaga Mahatmya: Trimurti Presence
ईश्वरः सर्वभूतानां यः पश्यति स पश्यति यत्नेनानेन तिष्ठन्ति ते यान्ति परमां गतिम् //
īśvaraḥ sarvabhūtānāṃ yaḥ paśyati sa paśyati yatnenānena tiṣṭhanti te yānti paramāṃ gatim //
He alone truly sees who beholds the Lord dwelling in all beings. Established in this disciplined effort, they attain the supreme destination—mokṣa (liberation).
It does not describe pralaya directly; instead it teaches the inner, timeless principle that liberation comes from perceiving the Supreme Lord present in all beings—knowledge that remains relevant regardless of cosmic creation or dissolution.
By urging the vision of Ishvara in all creatures, it supports ethical governance and household conduct—compassion, restraint, and fairness—since one who sees the Lord in all beings avoids harm and acts in dharma while pursuing the highest goal.
No explicit Vastu or ritual procedure is stated; the practical takeaway is devotional-dharmic orientation—rituals and temple acts are meant to culminate in this realization: seeing the Divine indwelling presence everywhere.
