Narayana said- Once Yashoda the wife of Nanda carried the child in her lap was feeding him with her breast milk.
In the meantime, all the cowherds and the old ladies together with boys and girls arrived in the abode of Nanda. At that point of time Yashoda placed the child who was still hungry over the bed and delightfully with pleasure started giving away the oil, vermilion, betel, sweets, clothes and ornaments on the occasion of the birthday of Krishna.
In the meantime, hungry Krishna started crying. In the meantime, Krishna the lord of illusion placed his foot with his illusion. His fort fell over the solid cart in the court-yard. With the blow of the foot of Krishna, the cart was shuttered into pieces which were scattered everywhere. The card, milk, ghee, butter and honey placed in the cart started flowing.
Looking at the surprise, the cowherdesses went running to the child. They found that he had been broken the cart into wooden pieces. All the vases of cart had been broken resulting into the flow of milk. With the remaining pieces, of wood. Feeling panicky, Yashoda removed the child from there, who’s all the limbs were intact with the influence of illusion. He was crying, simply because he was hungry. The grief stricken Yashoda started crying and also fed the child with her breast.
The cowherds enquired from the boys playing there. "How did this cart be broken"? We don’t find any reason for it. All of a sudden how could this surprise happen." On hearing this boy said, “O cowherds, you listen to our talk, the cart was broken with the attack of Krishna by his feet." On hearing this, all the cowherds and cowherdesses started laughing delightfully, who could not believe the same, the people of Vraja said that it was all false.
Thereafter the welfare ceremony of the child was performed by the Brahmanas. One of the Brahmanas placing his hand over the head of the child recited a kavacha.
О best of the Brahmanas, I am going to enlighten you about the kavacha with protects all. Its knowledge was imparted in earlier times by Yogamaya to Brahma when lord Vishnu was sleeping in the oceanic waters over the serpent bed and was terrified by Madhu-kaitabha, he recited the prayer to Yoganindra.
Yoganidra said- О lord of the universe, О Brahman, be fearless shedding the fear why should you be afraid when I and the lord are there. Therefore, you live comfortably.
Lord Hari should protect your face, Madhusudana should protect your forehead, Sri Krishna protect both your eyes. And the husband of Radhika should protect your nose.
Both the ears, the neck and the head should be protected by Madhava, the cheeks should be protected by Govinda and the hair should be protected by Keshava.
The lower lip should be protecting by Hrishikesha, the line of teeth should be protected by wielder of gada. The tongue should be protected by the lord of Rasa (dance) and the palate should be protected by Vamana the all-pervading one.
The chest should be protected by Mukunda and the belly should be protected by the killer of the Daityas, the navel should be protected by Janardana, while male organ should be protected by Vishnu. The pelvic region should be protected by Purushottma. The lord of Janaki should be protected the knees.
Nrusimha should protect both the hands during all the dangers. Varaha born out of lotus should protect the feet.
The bust should be protected by Narayana, while the lower portion should be protected by lord of Kamala, the eastern direction should be protected by Gopala or the south-east should be protected by the killer of Ravana, the southern region should be protected by Vanamali, south west should be protected by Vaikuntha while the western should be protected by Vasudeva.
North-west should be protected by Vishtarashrava. The northern direction should be protected by the lustre of Kamlasana and north east should be protected by Ishvara who should conquers of the enemies. Raghava should protect in the water land and the sky.
О Brahman, this is quite an astonishing kavacha the knowledge of which was bestowed on me by lord Krishna in earlier times.
Engaged in the terrific fight with Shumbha, goddess Durga on receiving this kavacha defeated the demon in no time.
With the influence of this kavacha he fell on the ground after have been killed. In the earlier times Shumbha carried on the war for a hundred years remaining in the sky and after his death lord Govinda while remaining in the sky bestowed this kavacha together with the rosary. And he went to Goloka thereafter.
О sage, I have narrated to you this kavacha with which no one gets panicky at any time.
In every kalpa with the company of the lord, I have seen crores of Brahmanas falling.
Thus, speaking handing over the kavacha, the goddess disappeared. Thereafter Brahma continued to dwell on the lotus emerging from navel of Vishnu.
This kavacha should be kept in gold and the intelligent people should it over the right arm and by doing so, one is relieved of the danger of poison, fire, water and enemies. The kavacha protect one in the waters on earth in the sky while sleeping or awake.
During the time of war, fall of thunderbolt, evil times and danger of death, one becomes fearless with the reciting of this kavacha.
In the earlier times by reciting this kavacha around his neck, Shiva easily over-powered Tripurasura and kicked him.
In the meantime, holding this kavacha, the goddess swallowed Raktabija and the Sesha with a thousand heads bears the load of the universe like the seed of Sesamum.
Both of us (Nara-Narayana), Sanatkumara, Dharma witness of the karmas are always victorious with the influence of this kavacha.
Thereafter Nanda, tied that kavacha round the neck of Krishna. Thus, lord Hari was adored with his own kavacha around his neck for protection.
O sage, I have narrated to you the influence of the kavacha of lord Hari and I am also narrating to the astonishing influence of lord Acyuta.
Summary of chapter 12 of the Brahma Vaivarta Mahā Purana - Śrī Kṛshṇa Janana Khaṇḍa is as follows:
Seeking astrological guidance for the divine child, Nanda Bābā invited the exalted sage Garga Muni to his home in Gokula. Conducting a private naming ceremony, Garga Muni whispered the secret truths of the child's divine identity to Nanda Bābā, revealing that this boy possessed the power of previous incarnations and would protect the universe from evil. Garga Muni formally named the elder boy Rāma due to his supreme strength and the younger dark-skinned child Kṛshṇa, warning Nanda Bābā to protect Him carefully as He would face many trials from wicked demons sent by Kaṃsa.
