The Appearance of Lord Viṣṇu (Kṛṣṇa) and the Divine Exchange with Yoga-māyā
तया हृतप्रत्ययसर्ववृत्तिषु द्वा:स्थेषु पौरेष्वपि शायितेष्वथ । द्वारश्च सर्वा: पिहिता दुरत्यया बृहत्कपाटायसकीलशृङ्खलै: ॥ ४८ ॥ ता: कृष्णवाहे वसुदेव आगते स्वयं व्यवर्यन्त यथा तमो रवे: । ववर्ष पर्जन्य उपांशुगर्जित: शेषोऽन्वगाद् वारि निवारयन् फणै: ॥ ४९ ॥
tayā hṛta-pratyaya-sarva-vṛttiṣu dvāḥ-stheṣu paureṣv api śāyiteṣv atha dvāraś ca sarvāḥ pihitā duratyayā bṛhat-kapāṭāyasa-kīla-śṛṅkhalaiḥ
By the influence of Yoga-māyā, all the doorkeepers fell fast asleep, their senses unable to work, and the other inhabitants of the house also fell deeply asleep. When the sun rises, the darkness automatically disappears; similarly, when Vasudeva appeared, the closed doors, which were strongly pinned with iron and locked with iron chains, opened automatically. Since the clouds in the sky were mildly thundering and showering, Ananta-nāga, an expansion of the Supreme Personality of Godhead, followed Vasudeva, beginning from the door, with hoods expanded to protect Vasudeva and the transcendental child.
Śeṣa-nāga is an expansion of the Supreme Personality of Godhead whose business is to serve the Lord with all necessary paraphernalia. When Vasudeva was carrying the child, Śeṣa-nāga came to serve the Lord and protect Him from the mild showers of rain.
This verse shows Yoga-māyā removing awareness and activity from guards and citizens, arranging sleep and sealed doors so Krishna’s pastime could unfold without obstruction.
So Vasudeva could carry the newborn Krishna safely; the Lord’s internal potency (Yoga-māyā) neutralized external danger and surveillance.
The verse teaches that when one serves the Lord sincerely, unseen support can arise—encouraging steadiness in devotion rather than fear-based living.
