Matsya Purana — Nārāyaṇa as Haṃsa in the Cosmic Ocean: Vedic Yajña-Puruṣa and Mārkaṇḍeya’s Vi...
मार्कण्डेयस्ततस्तस्य शनैर्वक्त्राद्विनिःसृतः स निष्क्रामन्न चात्मानं जानीते देवमायया //
mārkaṇḍeyastatastasya śanairvaktrādviniḥsṛtaḥ sa niṣkrāmanna cātmānaṃ jānīte devamāyayā //
Then Mārkaṇḍeya slowly emerged from his mouth. Yet, as he came out, by the power of divine illusion he did not recognize even his own self.
It implies a pralaya-like, reality-overturning condition where ordinary identity and self-recognition collapse under divine māyā—suggesting that cosmic events and inner perception can be radically transformed by the Lord’s power.
It cautions that status, role, and even self-certainty can be destabilized by illusion; therefore a king or householder should cultivate discernment (viveka), humility, and dharmic steadiness rather than relying on ego-based identity.
No direct Vastu or ritual rule is stated; the takeaway is theological—divine māyā can veil perception—often used in Purāṇic contexts to stress the need for correct ritual intent and inner clarity rather than mere external performance.
