The Lord says in Bhagavad-gītā (4.7):
yadā yadā hi dharmasya
glānir bhavati bhārata
abhyutthānam adharmasya
tadātmānaṁ sṛjāmy aham
“Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion — at that time I descend Myself.” Whenever Kṛṣṇa comes, once in a day of Brahmā, He comes to the house of Nanda Mahārāja in Vṛndāvana. Kṛṣṇa is the master of all creation (sarva-loka-maheśvaram). Therefore, not only in the neighborhood of Nanda Mahārāja’s estate, but all over the universe — and in all the other universes — musical sounds celebrated the auspicious arrival of the Lord.
