śulbaṁ sutasya na tu tat tad amuṣya māti
yaj jṛmbhato ’sya vadane bhuvanāni gopī
saṁvīkṣya śaṅkita-manāḥ pratibodhitāsīt
One day Lord Kṛṣṇa as the naughty child disturbed His mother Yaśodā, and she began to tie up the child with ropes just to punish Him. But no matter how much rope she used, she found it always insufficient. Thus she became fatigued, but in the meantime the Lord opened His mouth, and the affectionate mother saw within the mouth of her son all the universes situated together. The mother was astonished, but out of her deep affection for Kṛṣṇa she thought that the Almighty Godhead Nārāyaṇa had kindly looked after her son just to protect Him from all the continuous calamities happening to Him. Because of her deep affection for Kṛṣṇa, she could never think that her very son was Nārāyaṇa, the Personality of Godhead Himself. That is the action of yoga-māyā, the internal potency of the Supreme Lord, which acts to perfect all the pastimes of the Lord with His different types of devotees. Who could play such wonders without being God?
