Śrīla Prabhupāda said that we must start our science journal very soon.

"That is more important. Ordinary newspaper has no value. If you write in the scientific journal, then it will be very valuable. … You recruit all big, big scientists to write articles in our paper." [ibid]

He said that we should travel to different colleges and universities to convince people about the knowledge in the Vedas.

"That is called visva-vijaya. Formerly, learned scholars used to do that. Dig-vijaya. Dig-vijaya. "I have got this knowledge." You challenge, "Come on. Defeat me or I defeat you." So whoever is defeated, becomes a disciple. Dig-vijaya. Just like one dig-vijaya Panḍita came in Navadvipa to defeat the learned scholar of Navadvipa and Chaitanya Mahaprabhu defeated him. … So this was the system. So you go out, dig-vijaya. Travel all over the world. Now, you are qualified to speak. They must defeat you, or if they are defeated, they must become…, must accept. This is wanted, dig-vijaya Panḍita." [Room Conversations - Extra, Bhuvaneshwar, 2 February, 1977]

"Yes. All universities you go. All universities. You three or four go. Talk with them. Most, you write scholarly." [ibid]
