"Our movement is sarve sukhino bhavantu: everyone become, be happy. Not only human society, even animal society. We want to see everyone happy. That is Kṛṣṇa consciousness movement. And it is practical; it is not dream. You can become happy. Don't be disappointed, don't be confused. Your life has value. You, in this life, you can realize your eternal life, eternal blissful life of knowledge. It is possible; it is not impossible. So we are simply transmitting this message to the world, that 'Your life is very valuable. Don't waste it just like cats and dogs. Try to utilize it fully.' That is the statement in the Bhagavad-gītā. We have published Bhagavad-gītā As It Is. Try to read it. In that Bhagavad-gītā in the Fourth Chapter it is said, janma karma me divyaṁ yo jānāti tattvataḥ: if simply tries to understand what is Kṛṣṇa, what is His business, what is His life, where does He live, what does He do...., janma karma. Janma means appearance and disappearance; karma means activities; divyam—transcendental. Janma karma me divyaṁ yo jānāti tattvataḥ (BG 4.9). One who knows the appearance and activities of Kṛṣṇa in fact, in truth—not by sentiment but by scientific study—then the result is tyaktvā dehaṁ punar janma naiti mām eti kaunteya. Simply by understanding Kṛṣṇa, you'll no more have to come back to this miserable condition of material existence. This is fact. Even in your life, in this life, you'll understand, you'll be happy."
