Vasudeva: Son of King Śūrasena, husband of Devakī and father of Lord Śrī Kṛṣṇa. He is the brother of Kuntī and father of Subhadrā. Subhadrā was married with her cousin Arjuna, and this system is still prevalent in some parts of India. Vasudeva was appointed minister of Ugrasena, and later on he married eight daughters of Ugrasena's brother Devaka. Devakī is only one of them. Kaṁsa was his brother-in-law, and Vasudeva accepted voluntary imprisonment by Kaṁsa on mutual agreement to deliver the eighth son of Devakī. This was foiled by the will of Kṛṣṇa. As maternal uncle of the Pāṇḍavas, he took active parts in the purificatory process of the Pāṇḍavas. He sent for the priest Kaśyapa at the Śataśṛṅga Parvata, and he executed the functions. When Kṛṣṇa appeared within the bars of Kaṁsa's prison house, He was transferred by Vasudeva to the house of Nanda Mahārāja, the foster father of Kṛṣṇa, at Gokula. Kṛṣṇa disappeared along with Baladeva prior to the disappearance of Vasudeva, and Arjuna (Vasudeva's nephew) undertook the charge of the funeral ceremony after Vasudeva's disappearance.

Akrūra: The commander in chief of the Vṛṣṇi dynasty and a great devotee of Lord Kṛṣṇa. Akrūra attained success in devotional service to the Lord by the one single process of offering prayers. He was the husband of Sūtanī, daughter of Ahūka. He supported Arjuna when Arjuna took Subhadrā forcibly away by the will of Kṛṣṇa. Both Kṛṣṇa and Akrūra went to see Arjuna after his successful kidnapping of Subhadrā. Both of them presented dowries to Arjuna after this incidence. Akrūra was present also when Abhimanyu, the son of Subhadrā, was married with Uttarā, mother of Mahārāja Parīkṣit. Ahūka, the father-in-law of Akrūra, was not on good terms with Akrūra. But both of them were devotees of the Lord.

Pradyumna: Incarnation of Kāmadeva or, according to others, incarnation of Sanat-kumāra, born as the son of the Personality of Godhead Lord Śrī Kṛṣṇa and Lakṣmīdevī Śrīmatī Rukmiṇī, the principal queen at Dvārakā. He was one of those who went to congratulate Arjuna upon his marrying Subhadrā. He was one of the great generals who fought with Śālva, and while fighting with him he became unconscious on the battlefield. His charioteer brought him back to the camp from the battlefield, and for this action he was very sorry and rebuked his charioteer. However, he fought again with Śālva and was victorious. He heard all about the different demigods from Nāradajī. He is one of the four plenary expansions of Lord Śrī Kṛṣṇa. He is the third one. He inquired from his father, Śrī Kṛṣṇa, about the glories of the brāhmaṇas. During the fratricidal war amongst the descendants of Yadu, he died at the hand of Bhoja, another king of the Vṛṣṇis. After his death, he was installed in his original position.
(Srimad Bhagavatam-----1:11:16-17-----purport).

This is called vaibhava, or the transcendental potency of the Lord. And because He can do so, He is also known as Yogeśvara. Ordinarily, a yogī or mystic living being is able to expand himself at utmost to tenfold expansions of his body, but the Lord can do so to the extent of as many thousands or infinitely, as He likes. Unbelievers become astonished to learn that Lord Kṛṣṇa married more than 16,000 queens because they think of Lord Kṛṣṇa as one of them and measure the potency of the Lord by their own limited potency. One should know, therefore, that the Lord is never on the level of the living beings, who are but expansions of His marginal potency, and one should never equalize the potent and the potency, although there is very little difference of quality between the potent and the potency. The queens were also expansions of His internal potency, and thus the potent and potencies are perpetually exchanging transcendental pleasures, known as pastimes of the Lord. One should not, therefore, become astonished to learn that the Lord married so many wives. On the contrary, one should affirm that even if the Lord marries sixteen thousand million wives, He is not completely manifesting His unlimited and inexhaustible potency. He married only 16,000 wives and entered in each and every one of the different palaces just to impress in the history of the human beings on the surface of the earth that the Lord is never equal to or less than any human being, however powerful he may be. No one, therefore, is either equal to or greater than the Lord. The Lord is always great in all respects. "God is great" is eternal truth.
(Srimad Bhagavatam-----1:11:31-----purport).

The Lord married and lived like a householder. This is certainly like a mundane affair, but when we learn that He married 16,108 wives and lived with them separately in each and every palace, certainly it is not mundane. Therefore, the Lord, living as a householder amongst His competent wives, is never mundane, and His behavior with them is never to be understood as mundane sex relation. The women who became the wives of the Lord are certainly not ordinary women, because to get the Lord as one's husband is the result of many, many millions of births' tapasya (austerity). When the Lord appears on different lokas, or planets, or on this planet of human beings, He displays His transcendental pastimes just to attract the conditioned souls to become His eternal servitors, friends, parents and lovers respectively in the transcendental world, where the Lord eternally reciprocates such exchanges of service.
(Srimad Bhagavatam-----1:11:35-----purport).

The law of gravitation is binding upon him like the shackles of a prisoner. By other processes he can reach anywhere, but even if he reaches the highest planet, he cannot attain that perpetual happiness for which he is searching life after life. When he comes to his senses, however, he seeks after Brahman happiness, knowing it for certain that unlimited happiness, which he is seeking, is never attainable in the material world. As such, the Supreme Being, Para-brahman, certainly does not seek His happiness anywhere in the material world. Nor can His paraphernalia of happiness be found in the material world. He is not impersonal. Because He is the leader and Supreme Being amongst innumerable living beings, He cannot be impersonal. He is exactly like us, and He has all the propensities of an individual living being in fullness. He marries exactly like us, but His marriage is neither mundane nor limited by our experience in the conditioned state. His wives, therefore, appear like mundane women, but factually they are all transcendental liberated souls, perfect manifestations of internal energy.
(Srimad Bhagavatam-----1:11:35-----purport).

Such a conception is also the product of conditioned life because they cannot go beyond their own personal capacity. Therefore, one who considers the Lord on the level of one's limited potency is only a common man. Such a man cannot be convinced that the Personality of Godhead is always unaffected by the modes of material nature. He cannot understand that the sun is always unaffected by infectious matter. The mental speculators compare everything from the standpoint of experimental knowledge of their own selves. Thus when the Lord is found to act like an ordinary person in matrimonial bondage, they consider Him to be like one of them, without considering that the Lord can at once marry sixteen thousand wives or more. Due to a poor fund of knowledge they accept one side of the picture while disbelieving the other. This means that due to ignorance only they always think of Lord Kṛṣṇa as like themselves and make their own conclusions, which are absurd and unauthentic from the version of the Śrīmad-Bhāgavatam.
(Srimad Bhagavatam-----1:11:37-----purport).

Kṛpācārya is the son of the great Ṛṣi Sardban and was born in the family of Gautama. The birth is said to be accidental. By chance, the great Ṛṣi Sardban met Janapadī, a famous society girl of heaven, and the Ṛṣi Sardban discharged semina in two parts. By one part immediately a male child and by the other part a female child were born as twins. The male child was later on known as Kṛpa, and the female child was known as Kṛpī. Mahārāja Śantanu, while engaged in chase in the jungle, picked up the children and brought them up to the brahminical status by the proper purificatory process. Kṛpācārya later became a great general like Droṇācārya, and his sister was married to Droṇācārya. Kṛpācārya later on took part in the Battle of Kurukṣetra and joined the party of Duryodhana. Kṛpācārya helped kill Abhimanyu, the father of Mahārāja Parīkṣit, but he was still held in esteem by the family of the Pāṇḍavas due to his being as great a brāhmaṇa as Droṇācārya. When the Pāṇḍavas were sent to the forest after being defeated in the gambling game with Duryodhana, Dhṛtarāṣṭra entrusted the Pāṇḍavas to Kṛpācārya for guidance. After the end of the battle, Kṛpācārya again became a member of the royal assembly, and he was called during the birth of Mahārāja Parīkṣit for recitation of auspicious Vedic hymns to make the ceremony successful.
(Srimad Bhagavatam-----1:12:13-----purport).

Only the brāhmaṇas and sannyāsīs are authorized to accept charity from the householders. In all the different occasions of saṁskāras, especially during the time of birth, marriage and death, wealth is distributed to the brāhmaṇas because the brāhmaṇas give the highest quality of service in regard to the prime necessity of humankind. The charity was substantial in the shape of gold, land, villages, horses, elephants and food grains, with other materials for cooking complete foodstuff. The brāhmaṇas were not, therefore, poor in the actual sense of the term. On the contrary, because they possessed gold, land, villages, horses, elephants and sufficient grains, they had nothing to earn for themselves. They would simply devote themselves to the well-being of the entire society.
(Srimad Bhagavatam-----1:12:14-----purport).

The Lord is specifically the protector of the cows and the brāhmaṇas, and hence He enhances the prosperity of the world. Through the agency of Viśvāmitra He was rewarded by the administrative demigods with effective weapons to conquer the demons. He was present in the bow sacrifice of King Janaka, and by breaking the invincible bow of Śiva, He married Sītādevī, daughter of Mahārāja Janaka.
After His marriage He accepted exile in the forest for fourteen years by the order of His father, Mahārāja Daśaratha. To help the administration of the demigods, He killed fourteen thousand demons, and by the intrigues of the demons, His wife, Sītādevī, was kidnapped by Rāvaṇa. He made friendship with Sugrīva, who was helped by the Lord to kill Vāli, brother of Sugrīva. By the help of Lord Rāma, Sugrīva became the king of the Vāṇaras (a race of gorillas). The Lord built a floating bridge of stones on the Indian Ocean and reached Laṅkā, the kingdom of Rāvaṇa, who had kidnapped Sītā.
