Renunciation is not as important as enhancing one's attachment to Kṛṣṇa. The Kṛṣṇa consciousness movement is especially meant for this purpose. We are preaching the principle that it does not matter whether a man is a sannyāsī or gṛhastha (householder). One simply has to increase his attachment for Kṛṣṇa, and then his life is successful. Following in the footsteps of Lord Śrī Kṛṣṇa, one can live with his family members or within the society or nation, not for the purpose of indulging in sense gratification but to realize Kṛṣṇa by advancing in attachment for Him. There are four principles of elevation from conditioned life to the life of liberation, which are technically known as dharma, artha, kāma and mokṣa (religion, economic development, sense gratification and liberation). If one lives a family life following in the footsteps of Lord Kṛṣṇa's family members, one can achieve all four of these principles of success simultaneously by making Kṛṣṇa the center of all activities.
It is already known to us that Kṛṣṇa had 16,108 wives. All these wives were exalted liberated souls, and among them Queen Rukmiṇī was the chief. After Rukmiṇī there were seven other principal wives, and the names of the sons of these eight principal queens have already been mentioned. Besides the sons born of these eight queens, Lord Kṛṣṇa had ten sons by each of the other queens. Thus altogether Kṛṣṇa's sons numbered 16,108 times ten. One should not be astonished to hear that Kṛṣṇa had so many sons. One should always remember that Kṛṣṇa is the Supreme Personality of Godhead and that He has unlimited potencies. He claims all living entities as His sons, so the fact that He had 161,080 sons attached to Him personally should be no cause for astonishment.
Among Kṛṣṇa's greatly powerful sons, eighteen sons were mahā-rathas. The mahā-rathas could fight alone against many thousands of foot soldiers, charioteers, cavalry and elephants. The reputations of these eighteen sons are very widespread and are described in almost all the Vedic scriptures. The eighteen mahā-ratha sons are listed as Pradyumna, Aniruddha, Dīptimān, Bhānu, Sāmba, Madhu, Bṛhadbhānu, Citrabhānu, Vṛka, Aruṇa, Puṣkara, Vedabāhu, Śrutadeva, Sunandana, Citrabāhu, Virūpa, Kavi and Nyagrodha. Of these eighteen mahā-ratha sons of Kṛṣṇa, Pradyumna is considered the foremost. Pradyumna happened to be the eldest son of Queen Rukmiṇī, and he inherited all the qualities of his great father, Lord Kṛṣṇa. He married the daughter of his maternal uncle, Rukmī, and from that marriage Aniruddha was born. Aniruddha was so powerful that he could fight against ten thousand elephants. He married the granddaughter of Rukmī, the brother of his grandmother Rukmiṇī. Because the relationship between these cousins was distant, such a marriage was not uncommon. Aniruddha's son was Vajra. When the whole Yadu dynasty was destroyed by the curse of some brāhmaṇas, only Vajra survived. Vajra had one son, whose name was Pratibāhu. The son of Pratibāhu was named Subāhu, the son of Subāhu was named Śāntasena, and the son of Śāntasena was Śatasena.
It is stated by Śukadeva Gosvāmī that all the members of the Yadu dynasty had many children. Just as Kṛṣṇa had many sons, grandsons and great-grandsons, each one of the kings named herewith also had similar family extensions. Not only did all of them have many children, but all were extraordinarily rich and opulent. None of them were weak or short-lived, and above all, all the members of the Yadu dynasty were staunch devotees of the brahminical culture. It is the duty of the kṣatriya kings to maintain the brahminical culture and protect the qualified brāhmaṇas, and all these kings discharged their duties rightly. The members of the Yadu dynasty were so numerous that it would be very difficult to describe them all, even if one had a duration of life of many thousands of years. Śrīla Śukadeva Gosvāmī informed Mahārāja Parīkṣit that he had heard from reliable sources that simply to teach the children of the Yadu dynasty there were as many as 38,800,000 tutors, or ācāryas. If so many teachers were needed to educate their children, one can simply imagine how vast was the number of family members. As for their military strength, it is said that King Ugrasena alone had ten quadrillion soldiers as personal bodyguards.
Before the advent of Lord Kṛṣṇa within this universe, there were many battles between the demons and the demigods. Many demons died in the fighting, and they all were given the chance to take birth in high royal families on this earth. Because of their royal exalted posts, all these demons became very much puffed up, and their only business was to harass their subjects. Lord Kṛṣṇa appeared on this planet just at the end of Dvāpara-yuga to annihilate all these demoniac kings. As it is said in the Bhagavad-gītā, paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām: (BG 4.8) "The Lord comes to protect the devotees and annihilate the miscreants." Some of the demigods were asked to appear on this earth to assist in the transcendental pastimes of Lord Kṛṣṇa. When Kṛṣṇa appeared, He came in the association of His eternal servitors, but some of the demigods also were requested to come down to assist Him, and thus they took their births in the Yadu dynasty. The Yadu dynasty had 101 clans in different parts of the country. All the members of these different clans respected Lord Kṛṣṇa in a manner befitting His divine position, and all of them were His devotees heart and soul. Thus all the members of the Yadu dynasty were very opulent, happy and prosperous, and they had no anxieties. Because of their implicit faith in and devotion to Lord Kṛṣṇa, they were never defeated by any other kings. Their love for Kṛṣṇa was so intense that in their regular activities—in sitting, sleeping, traveling, talking, sporting, cleansing, bathing—they were simply absorbed in thoughts of Kṛṣṇa and paid no attention to bodily necessities. That is the symptom of a pure devotee of Lord Kṛṣṇa. Just as when a man is fully absorbed in some particular thought he sometimes forgets his other bodily activities, the members of the Yadu dynasty acted automatically for their bodily necessities, but their actual attention was always fixed on Kṛṣṇa. Their bodily activities were performed mechanically, but their minds were always absorbed in Kṛṣṇa consciousness.
