If you actually want to go to the moon planet, there is a clear process. A long time ago — I think sometime in 1960 — I wrote the book Easy Journey to Other Planets.

So one gentleman met me: “Sir, your book, Easy Journey . . . So we shall go there?”

“Yes, we shall go.”

“And again I shall come back?”

“No. No coming back.” [Chuckles.]

So he replied, “Then what is the use of going?”

That means he wants to go only for sense gratification. He wants to go to the moon or any planet, come back, and boast amongst his friends, “You see, I have gone.” [Laughter.]

That is his business. Actually, he doesn’t want to go there, nor has he got the power to go, but he wants to satisfy his senses. “I shall go there and come back and show my very swollen chest – ‘I have gone to the moon.'”
