I watched the following video to see whether it sheds some light on the cosmological model found in the Bhagavatam; however, I found that the video gave a different cosmological model and called it a part of Vedic cosmology that can be found in the Vedic literature. Here is the model:
Chandra Mandal, whose lok is Chandra lok (moon) revolves around the Bhu Mandal, whose lok is Bhu lok. Bhu Mandal revolves around the Surya Mandal whose lok is the sun; it is also called svarg in the video. The space in between Bhu Mandal and Surya Mandal is called Bhuva. Bhu + Bhuva + Svarg creates the first triloki.
The Surya Mandal revolves around the Paramesthi Mandal, whose lok is Jana lok. The space in between is called Maha, and Svarg + Maha + Jana creates the second triloki.
The Paramesthi Mandal revolves around the Svyambhu Mandal whose lok is Satya loka, the abode of Lord Brahma. The space in between is called Tapa, and Jana + Tapa + Satya created the third triloki
Some of the names match those found in the Bhagavatam, but I do not find any mentions about the mandalas rotating about other mandalas. What Vedic literature mentions the model stated in the video?
