Śyāmasundara: The seven planetary systems, do they correspond to the seven colors and the seven jewels of the yogi?
Prabhupāda: No. There is seven planetary systems over us and seven planetary systems down also. Therefore this universe is called caturdaśa-bhuvana: (indistinct) "Fourteen planetary systems." This is called Bhūrloka. Above this, there is Bhuvarloka. Above that, there is Janaloka. Above that, there is Maharloka. Above that, there is Satyaloka. Above that, there is Brahmaloka, the highest planetary system. Similarly, down also, we have got Tala, Atala, Talātala, Vitala, Pātāla, Rasātala. This information we get from Vedic literature, fourteen worlds. Each and every universe is consisting of these fourteen planetary systems, and there are innumerable universes. So that we also get information from Brahma-saṁhitā. Yasya prabhā prabhavato jagad-aṇḍa-koṭi (BS 5.40). Jagad-aṇḍa-koṭi. Jagad-aṇḍa means this universe is a big, I mean to say, volume. Just like aṇḍa, egg. Everything, every planet is just like egg. This brahmāṇḍa, this universe, is also like egg. So there are many many, many millions of jagad-aṇḍa. And in each and every jagad-aṇḍa, koṭiṣu vasudhādi-vibhūti-bhinnam, there are innumerable planets also. So these are the information we get from Vedic literature. If you like, you can accept. If you don't like you can reject. That is up to you.
