By incarnating within the Yadu dynasty, Kṛṣṇa performed the highest welfare work for the entire universe by displaying His transcendental pastimes. Simply by hearing and chanting about these pastimes, pious persons in Kali-yuga can definitely cross over the ocean of material illusion. When the Lord had fulfilled the purpose of His descent and the Yadu dynasty was facing imminent destruction from the brāhmaṇas’ curse, the Lord desired to wind up His pastimes. When Brahmā prayed to the lotus feet of Lord Kṛṣṇa for the deliverance of himself and all the other demigods, Śrī Kṛṣṇa revealed in His reply that after the destruction of the Yadu dynasty He would return to His own abode.
