The highest planetary system, spiritual, that is spiritual planet, that is named goloka-nāmni, Goloka Vṛndāvana. We have given that picture in the Bhāgavata cover. Perhaps you know. The topmost original planet is the Goloka. Goloka-nāmni nija-dhāmni. That is the abode of Kṛṣṇa, kṛṣṇa-dhāma. Kṛṣṇa-dhāma. People are searching after God, but actually there is the planet where God lives, Kṛṣṇa lives. But you have got your machine, aeroplane, sputnik.
You can reach there. But you cannot reach even the highest planet even on this material planet, material universe. Everyone sees. We see the stars or planets. Now you have got the machine; you go there. No. You cannot go. You are so limited. Even you cannot go to the moon planet, which is so nearest. You cannot go. But still, we are proud of our these airplanes, sputniks. We are thinking, "Now we have become God."
These rascals they do not know what is God. They are all rascals. They have no idea what is God. Therefore they have accepted another rascal as God. This is going on. You cannot reach. Panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi manaso muni-puṅgavānām, so 'pyasti yat prapada-sīmny avicintya-tattve (Bs. 5.34), śāstra gives you. Just like your material science also gives you information that there is one planet, highest planet, and one can go there by sputnik in forty thousands of years. So who is going to live forty thousand years to reach there? But they have got theoretically all these things. The highest planet. Material. That is not spiritual.
