Just like the Buddhists, they have got very . . . now, those who are not practicing, that is different thing. But rules and regulation, Lord Buddha himself, he showed. He left his everything and became engaged in simply meditation. Who is doing that? Nobody is doing that. Śaṅkarācārya's first condition is that "First of all you take sannyāsa; then you talk of becoming Nārāyaṇa."
Who is taking sannyāsa? So they are simply falsely thinking. Actually, their intelligence is impure, consciousness is impure. Therefore in spite of such endeavorance, the result is āruhya kṛcchreṇa param. Although they go very high, say 25,000 miles or millions of miles up, they do not find any shelter, where is moon planet, where is . . . they come down again to your Moscow city, that's all. Or New York City, that's all. These are the examples.
When they're high up, oh, they'll take photograph, "Oh, this planet is so . . . this earthly planet is so green or so small. I am going round day and night and seeing in one hour three times day and night." All right, very good. Please come down again. (laughs) That's all. Māyā is so strong, she will say: "Yes, very good. You are very advanced in your scientific knowledge, but please come down. Come here. Otherwise you are going to be put into the Atlantic Ocean." That's all.
And they'll still be puffed up, "Oh, we are making progress. Within next ten years, you can purchase ticket or land in the moon." You know, in Russia they sold land, and they advertised that, "There is Sea of Moscow. We have planted our flag on the sea in the . . ." So these are propaganda. They cannot go even into the nearest planet, what to speak of the spiritual sky. If you actually serious of going to the spiritual sky and Vaikuṇṭhaloka, then take this simple method, Hare Kṛṣṇa. That's all.
