Before Lord Kṛṣṇa appeared, many demons took birth in human families to harass the people of the world and destroy brahminical culture. To subdue them, the Lord ordered the demigods to descend into the Yadu dynasty, which then expanded into 101 clans. All of the Yadus recognized Śrī Kṛṣṇa as the Supreme Personality of Godhead and had unflinching faith in Him. While resting, eating, walking and so on, which they often did in His company, they would forget their own bodies in their transcendental happiness.
