The inhabitants of Vṛndāvana—the gopīs, mother Yaśodā, Nanda Mahārāja, the cowherd boys, the cows and everyone else—are actually on the rāga-mārga or bhāgavata-mārga platform. They participate in five basic rasas-dāsya, sakhya, vātsalya, mādhurya and śānta. But although these five rasas are found in the bhāgavata-mārga, the bhāgavata-mārga is especially meant for vātsalya and mādhurya, or paternal and conjugal relationships.
(Srimad Bhagavatam----4:24:45:46----purport).

The Supreme Personality of Godhead is called ajita, meaning that no one can conquer Him, but a devotee, by strong devotional service and sincere attachment to the Supreme Personality of Godhead, can easily conquer Him. Lord Kṛṣṇa is fear personified for everyone, but He voluntarily agreed to fear the stick of mother Yaśodā. Kṛṣṇa, God, cannot be conquered by anyone but His devotee.
(Srimad Bhagavatam----4:28:29----purport).

No living entity is free from the cycle of birth and death unless he takes to Kṛṣṇa consciousness; therefore in this verse it is clearly stated (sattvaika-niṣṭhe) that when one is fully absorbed in Kṛṣṇa consciousness, in one stroke he is freed of past and future mental desires. Then, by the grace of the Supreme Lord, everything becomes simultaneously manifest within the mind. In this regard, Viśvanātha Cakravartī Ṭhākura cites the example of mother Yaśodā's seeing the whole cosmic manifestation within the mouth of Lord Kṛṣṇa. By the grace of Lord Kṛṣṇa, mother Yaśodā saw all the universes and planets within the mouth of Kṛṣṇa. Similarly, by the grace of the Supreme Personality of Godhead, Kṛṣṇa, a Kṛṣṇa conscious person can see all his dormant desires at one time and finish all his future transmigrations. This facility is especially given to the devotee to make his path clear for returning home, back to Godhead.
(Srimad Bhagavatam----4:26:69----purport).

"Lord Caitanya replied, 'Lord Kṛṣṇa has a specific characteristic. He attracts everyone's heart by the mellow of His personal conjugal love. By following in the footsteps of the inhabitants of the planet known as Vrajaloka or Goloka Vṛndāvana, one can attain the shelter of the lotus feet of Śrī Kṛṣṇa. However, the inhabitants of that planet do not know that Lord Kṛṣṇa is the Supreme Personality of Godhead. Unaware that Kṛṣṇa is the Supreme Lord, the residents of Vṛndāvana like Nanda Mahārāja, Yaśodādevī and the gopīs treat Kṛṣṇa as their beloved son or lover. Mother Yaśodā accepts Him as her son and sometimes binds Him to a grinding mortar. Kṛṣṇa's cowherd boy friends think He is an ordinary boy and get up on His shoulders. In Goloka Vṛndāvana no one has any desire other than to love Kṛṣṇa.' "
(Srimad Bhagavatam----5:18:23----purport).

Sometimes the Lord, as the child of mother Yaśodā, requests His devotee for some food, as if He were very hungry. Sometimes He tells His devotee in a dream that His temple and His garden are now very old and that He cannot enjoy them very nicely. Thus He requests the devotee to repair them. Sometimes He is buried in the earth, and as if unable to come out Himself, He requests His devotee to rescue Him. Sometimes He requests His devotee to preach His glories all over the world, although He alone is quite competent to perform this task. Even though the Supreme Personality of Godhead is endowed with all possessions and is self-sufficient, He depends on His devotees. Therefore the relationship of the Lord with His devotees is extremely confidential.
(Srimad Bhagavatam----6:19:5----purport).

When Kṛṣṇa is away from Vṛndāvana tending the cows in the forest, the gopīs, in the mādhurya-rasa, are always absorbed in thoughts of how Kṛṣṇa walks in the forest. The soles of His feet are so soft that the gopīs would not dare keep His lotus feet on their soft breasts. Indeed, they consider their breasts a very hard place for the lotus feet of Kṛṣṇa, yet those lotus feet wander in the forest, which is full of thorny plants. The gopīs are absorbed in such thoughts at home, although Kṛṣṇa is away from them. Similarly, when Kṛṣṇa plays with His young friends, mother Yaśodā is very much disturbed by thoughts that Kṛṣṇa, because of always playing and not taking His food properly, must be getting weak. These are examples of the exalted ecstasy felt in Kṛṣṇa's service as manifested in Vṛndāvana.
(Srimad Bhagavatam----7:1:27----purport).

Kṛṣṇa's smiling face, with His cheeks, His lips, the ornaments in His ears, His chewing of betel nuts—all this was minutely observed by the gopīs, who thus enjoyed transcendental bliss, so much so that they were never fully satisfied to see Kṛṣṇa's face, but instead condemned the creator of the body for making eyelids that obstructed their vision. The beauty of Kṛṣṇa's face was therefore much more appreciated by the gopīs than by His friends the cowherd boys or even by Yaśodā Mātā, who was also interested in decorating the face of Kṛṣṇa.
(Srimad Bhagavatam----9:24:65----purport).

By the blessings of Kṛṣṇa, Yogamāyā became the daughter of mother Yaśodā, but by the supreme will she was not able to enjoy the parental love of her father and mother. Kṛṣṇa, however, although not actually born from the womb of mother Yaśodā, enjoyed the parental love of mother Yaśodā and Nanda. By the blessings of Kṛṣṇa, Yogamāyā was able to achieve the reputation of being the daughter of mother Yaśodā, who also became famous by the blessings of Kṛṣṇa. Yaśodā means "one who gives fame."
(Srimad Bhagavatam----10:2:9----purport).

The Lord then decided to leave the residence of Vasudeva and Devakī, in the prison house of Kaṁsa, and at this very time, Yogamāyā took birth as the daughter ofYaśodā. By the arrangement of Yogamāyā, Vasudeva was able to leave the prison house and save the child from the hands of Kaṁsa. When Vasudeva brought Kṛṣṇa to the house of Nanda Mahārāja, he saw that by Yogamāyā's arrangement, Yaśodā, as well as everyone else, was deeply asleep. Thus he exchanged the babies, taking Yogamāyā from Yaśodā's lap and placing Kṛṣṇa there instead. Then Vasudeva returned to his own place, having taken Yogamāyā as his daughter. He placed Yogamāyā on Devakī's bed and prepared to be a prisoner as before. In Gokula, Yaśodā could not understand whether she had given birth to a male or a female child.
(Srimad Bhagavatam----10:3--summary).

Nanda Mahārāja and Vasudeva were intimate friends, and so were their wives, Yaśodā and Devakī. Although their names were different, they were practically nondifferent personalities. The only difference is that Devakī was able to understand that the Supreme Personality of Godhead had been born to her and had now changed into Kṛṣṇa, whereas Yaśodā was not able to understand what kind of child had been born to her. Yaśodā was such an advanced devotee that she never regarded Kṛṣṇa as the Supreme Personality of Godhead, but simply loved Him as her own child.
(Srimad Bhagavatam----10:3:53----purport).

The jāta-karma ceremony can take place when the umbilical cord, connecting the child and the placenta, is cut. However, since Kṛṣṇa was brought by Vasudeva to the house of Nanda Mahārāja, where was the chance for this to happen? In this regard, Viśvanātha Cakravartī Ṭhākura desires to prove with evidence from many śāstras that Kṛṣṇa actually took birth as the son of Yaśodā before the birth of Yogamāyā, who is therefore described as the Lord's younger sister. Even though there may be doubts about the cutting of the umbilical cord, and even though it is possible that this was not done, when the Supreme Personality of Godhead appears, such events are regarded as factual. Kṛṣṇa appeared as Varāhadeva from the nostril of Brahmā, and therefore Brahmā is described as the father of Varāhadeva. Also significant are the words kārayām āsa vidhivat. Being overwhelmed with jubilation over the birth of his son, Nanda Mahārāja did not see whether the cord was cut or not. Thus he performed the ceremony very gorgeously. According to the opinion of some authorities, Kṛṣṇa was actually born as the son of Yaśodā. In any case, without regard for material understandings, we can accept that Nanda Mahārāja's celebration for the ceremony of Kṛṣṇa's birth was proper. This ceremony is therefore well known everywhere as Nandotsava.
(Srimad Bhagavatam----10:5:1-2----purport).

When Śrī Kṛṣṇa was only three months old and was just trying to turn backside up, before He even attempted to crawl, mother Yaśodā wanted to observe a ritualistic ceremony with her friends for the good fortune of the child. Such a ritualistic ceremony is generally performed with ladies who also have small children. When mother Yaśodā saw that Kṛṣṇa was falling asleep, because of other engagements she put the child underneath a household cart, called śakaṭa, and while the child was sleeping, she engaged herself in other business pertaining to the auspicious ritualistic ceremony. Underneath the cart was a cradle, and mother Yaśodā placed the child in that cradle. The child was sleeping, but suddenly He awakened and, as usual for a child, began to kick His small legs. This kicking shook the cart, which collapsed with a great sound, breaking completely and spilling all its contents. Children who were playing nearby immediately informed mother Yaśodā that the cart had broken, and therefore she hastily arrived there in great anxiety with the other gopīs. Mother Yaśodāimmediately took the child on her lap and allowed Him to suck her breast. Then various types of Vedic ritualistic ceremonies were performed with the help of the brāhmaṇas. Not knowing the real identity of the child, the brāhmaṇas showered the child with blessings.
(Srimad Bhagavatam----10:7----summary).

Another day, when mother Yaśodā was sitting with her child on her lap, she suddenly observed that he had assumed the weight of the entire universe. She was so astonished that she had to put the child down, and in the meantime Tṛṇāvarta, one of the servants of Kaṁsa, appeared there as a whirlwind and took the child away.
(Srimad Bhagavatam----10:7----summary).

The demon having fallen, the gopīs picked the child up and delivered Him to the lap of mother Yaśodā. Thus mother Yaśodā was struck with wonder, but because of yogamāyā's influence, no one could understand who Kṛṣṇa was and what had actually happened. Rather, everyone began to praise fortune for the child's having been saved from such a calamity. Nanda Mahārāja, of course, was thinking of the wonderful foretelling of Vasudeva and began to praise him as a great yogī. Later, when the child was on the lap of mother Yaśodā, the child yawned, and mother Yaśodā could see within His mouth the entire universal manifestation.
