The Buddha told the monks, “On the right side of Mount Himavat, there’s a city named Vaiśālī. That city has seven black mountains to its north. North of those seven black mountains, there’s a fragrance mountain. There are always sounds of music and singing at that mountain. It has two caves: One is called Painted and the second is called Skillfully Painted. They’re made of seven heavenly treasures that are soft and pleasant smelling like heavenly cloth. The Gandharva King Sarasvatī lives there with 500 gandharvas.
