PURPORT

The Nagaloka planet is situated below the earth planet and it is understood that the sunray is hampered there. The darkness of the planet is however removed by flashes of the jewels set on the heads of the Nagas and it is said that there are beautiful gardens, revulets etc. for the enjoyment of the Nagas. It is understood here also that the place is well protected by the inhabitants. So also the city of Dwarka was being well protected by the descendants of Vrishni who were equally powerful like the Lord so far He manifested His strength within this earth.
