The Brahmavaivarta Purana, Krishna-Janma-Khanda 185.180 states:
asvamedham gavalambham sannyasam palapaitrkam devarena sutopattim kalau panca vivarjayet
Five things are forbidden in the age of Kali – horse-sacrifice, cow-sacrifice, acceptance of sannyasa, offering flesh to the forefathers and begetting a child in the womb of the wife of one’s elder brother.
As you can see the above verse forbids accepting sannyasa in Kali-Yuga. I want to know whether any other scripture apart from the Brahmavaivarta Purana forbids sannyasa?
