So I also came for that purpose, because our modern India has rejected the spiritual knowledge. They are thinking that if they can imitate westernized technology, then they will be happy. This is māyā. They do not see that those who are advanced three hundred times more than us in technology, what they have got? They do not see that. India cannot advance in technology like America or Europe at least for three hundred years more, because in these Western countries they have taken this business since a very long time.
But Indian culture, beginning from the creation, is spiritual culture. Vyāsadeva . . . just see Vyāsadeva. He is the original guru, spiritual master, of Vedic knowledge. How he was living? In a cottage in Badarikāśrama. But just see his knowledge. He has written so many Purāṇas, and Bhāgavata Purāṇa is one of them. The Vedānta philosophy, Mahābhārata, each and every verse if you study, you can study for the whole life. Similarly, in some book he has written 100,000's of verses, not less than 20,000, 25,000 verses. And each verse is so full of meaning that one has to learn it throughout his whole life. This is Vedic culture.
There is no comparison of knowledge, not only in spiritual knowledge, in other department also—in astronomy, in mathematics. It is not that in the olden age there were no aeroplanes. We get so many information from Purāṇas. Their aeroplane was so strong and so, I mean to say, speedy, they could easily reach other planets. Arjuna went to the heavenly planet.
So material knowledge, advancement, is not that there was no advancement of material knowledge in the Vedic age. It was there, but they did not take much care of it. They were interested for spiritual knowledge. It is not that material knowledge was not there. It was there. The opulence . . . that opulence you cannot compare now. Gold, jewels, full—every city, every individual person, and what to speak of kings and rich men.
