Man on the Moon? Very old concept!

"In these days, when men are trying to go to the moon, people should not think that Kṛṣṇa consciousness is concerned with something old-fashioned. When the world is progressing to reach the moon, we are chanting Hare Krishna. But people should not misunderstand and assume that we are lagging behind modern scientific advancement. We have already passed all scientific advancement. In Bhagavad-gītā it is said that man's attempt to reach higher planets is not new.

Newspaper headlines read, "Man's First Steps on the Moon," but the reporters do not know that millions and millions of men went there and came back. This is not the first time. This is an ancient practice. In Bhagavad-gītā (8.16) it is clearly stated, abrahma-bhuvanāl lokāḥ punar āvartino 'rjuna: "My dear Arjuna, even if you go to the highest planetary system, which is called Brahmaloka, you will have to come back." Therefore, interplanetary travel is not new. It is known to the Kṛṣṇa conscious devotees."
