(Vishnujana Swami, a dear disciple of Srila Prabhupada)
"Our Kṛṣṇa consciousness movement is to produce some great souls. If people get opportunity to associate with great souls, then automatically his path of liberation will be open. Mahat-sevāṁ dvāram āhur vimukteḥ (SB 5.5.2). And tamo-dvāraṁ yoṣitāṁ saṅgi-saṅgam. And if you associate with persons who are simply interested in sense gratification, then you must know that your door for going into the darkest region of ignorance is open. Two doors: one door to the path of liberation, and one door to the path of darkest region of ignorance. That means material existence. You know, in the material existence... Just like we are also living entities, and the cockroaches are also living entities. Do you know where they are living? Within the commode there are many germs, many worms, they are also living entities. They're stool. There are worms in the stool. They're also living entities. So we can fall down up to that point even. Don't think that because we have got this beautiful body, nice situation, this is guarantee of any falldown. No. We can fall down any moment, in any species of life. There are 8,400,000 species of life. You should know it. And utilize this opportunity for opening the door of liberation. Mahat-sevāṁ dvāram āhur vimukteḥ (SB 5.5.2). And in order to reach to that door of liberation, you have to associate with persons who are devotees of Lord, mahat-sevā. Mahat-sevāṁ dvāram āhur vimuktes tamo-dvāraṁ yoṣitāṁ saṅgi-saṅgam. Yoṣitām. If I simply avoid, myself, the process of sense gratification, but if I associate with persons who are addicted to sense gratification, then that is also very dangerous. That is also very dangerous, because saṅgāt sañjāyate kāmaḥ—my desires and my propensities will develop according to the association I make. A man is known by his company.
So this Kṛṣṇa conscious movement, this opening of different centers, is meant for giving association to the people in general for opening the door of liberation. That is a fact. You try to understand by all your arguments, reason and logic. And inquiry. That is a fact, because we are presenting authorized thing. So my request is that you take advantage. You have got good opportunity. You take this advantage of opening the door of liberation and don't misuse your life simply for sense gratification like cats and dogs. Then the people of your country, of your society or your family, they'll be all benefited, and because other nations, they are also imitating your procedures, they'll be benefited. And at least if one percent of the whole population becomes Kṛṣṇa conscious, the whole world will be a different world. There will be... The world itself will become kingdom of God. Of course, we cannot expect that everyone will accept this philosophy, but we are trying. If some percentage of the population takes this movement seriously, the face of the world will be changed."
