Now, if you go to another island, there also you will find the same varieties as you find here. Similarly, if you go to other planet, you will find the same varieties as here. Maybe little different, climatic, but the quality of variety is the same. There is no reason to believe that there is no life, no variegated. This is all nonsense. If I come from the mainland of America, USA, to this island, I'll find the same trees or same population and same working. What is the reason to believe that there is no life, there is no vegetable? Why? This is lack of knowledge. Everywhere the same varieties. And wherefrom the varieties are coming? From the sunshine. That is fact, scientific.
Because the sunshine is there, so many varieties of planet are coming out, and in each and every planet there are so many varieties of vegetation, human being, animals, seas, mountain. And similarly... This is explained in the Brahma-saṁhitā: yasya prabhā prabhavato jagad-aṇḍa-koṭi [Bs. 5.40]. Yasya prabhā.
These innumerable universes, how they have been possible? How they are existing? That is explained in the Brahma-saṁhitā, "On account of Kṛṣṇa's effulgence." You see Kṛṣṇa. When Kṛṣṇa is sitting, you will find effulgence. That effulgence, it is so full of potencies. Same way, as the sunlight, sunshine, is so full of potencies—they are producing so many planets, varieties—similarly, you can understand how much Kṛṣṇa's effulgence, that shining from His body, is potential. So that is stated in the Brahma-saṁhitā. Coming out universes. And within the universes there are planets, and within the planet there are so many varieties, and within the varieties there are so many differentiation.
