## Third Rebirth: Four Types of World-Ending Beings
[195] Gautama! The name of the second earth is Vansa and its gotra is Sharkaraprabha. In this way, you should ask questions about all the earths. Their names are as follows: the name of the third earth is Shaila, the name of the fourth earth is Anjana, the name of the fifth earth is Ristha, the name of the sixth earth is Magha, and the name of the seventh earth is Maghavati.
The gotra of the third earth is Balukaprabha, the gotra of the fourth earth is Pankaprabha, the gotra of the fifth earth is Dhumarprabha, the gotra of the sixth earth is Tamahprabha, and the gotra of the seventh earth is Tamas-tamahprabha.
