We have no information in this age, at the present time, what is that spiritual world, but they are all stated in the Bhagavad-gītā: paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ (BG 8.20). Everything is there in the Bhagavad-gītā. Bhagavad-gītā is the preliminary study of spiritual life, A-B-C-D of spiritual life. The people cannot understand even the A-B-C-D of Bhagavad-gītā, and Śrīmad-Bhāgavatam is the graduate study. So everything is there. Unfortunately it was not distributed. So our Kṛṣṇa consciousness movement has started to distribute this literature, especially Śrīmad-Bhāgavatam. We have already translated about twenty books. They are present before you, and our aim is to present to the human society sixty books. Still translation is going on. So our request to the publishers and booksellers that, "Let this literature be distributed properly. People will be benefited."
Because, after all, each and every human being is a spiritual being. He is not this body. That is the mistake of the present civilization. Yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13). Ātma-buddhi, "self." People, everyone thinks that this body, "I am this body." If I ask any gentleman, "What you are?" He'll say: "I am Mr. Such-and-such. I am born in this country." "I am American," "I am Englishman," "I am Indian." These are all bodily description. But basically I am not this body. This is called illusion. You have got practical experience. When one man's father or son or any relative dies, he cries, "Oh, my son has gone away," "My father has gone away." Then, "Your father is lying there on the bed. How do you say that, 'My father has gone away'? " That means the actual father, he has never seen. He has seen the body only. And on this bodily conception of life, everything is being manipulated. This is called illusion.
