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 Krṣṇa 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 Krṣṇa appeared on this planet just at the end of Dvāpara-yuga in order to annihilate all these demonic kings. As it is said in the  Bhagavad-gītā ,  paritrāṇāya sādhūnām vināśāya ca duṣkṛtām : The Lord comes to protect the devotees and to annihilate the miscreants. Some of the demigods were also asked to appear on this earth to assist in the transcendental pastimes of Lord Krṣṇa. When Krṣṇa appeared, He came in the association of His eternal servitors, but the demigods also were requested to come down to assist Him, and thus all of them 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 Krṣṇa 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 Krṣṇa, they were never defeated by any other kings. Their love of Krṣṇa was so intense that in their regular activities—in sitting, sleeping, traveling, talking, sporting, cleansing and bathing—they were simply absorbed in thoughts of Krṣṇa and paid no attention to bodily necessities. That is the symptom of a pure devotee of Lord Krṣṇa. Just as when a man is fully absorbed in some particular thought, he sometimes forgets his other bodily activities, so the members of the Yadu dynasty acted automatically for their bodily necessities, but their actual attention was always fixed on Krṣṇa. Their bodily activities were performed mechanically, but their minds were always absorbed in Krṣṇa consciousness.
Śrīla Śukadeva Gosvāmī has concluded the Ninetieth Chapter of the Tenth Canto of  Śrīmad-Bhāgavatam  by pointing out five particular excellences of Lord Krṣṇa. The first excellence is that before Lord Krṣṇa's appearance in the Yadu family, the River Ganges was known as the purest
