So the conclusion is that if people become simply atheistic or materialistic... Materialistic means atheistic. And then the weight of the earth, or any planet, will increase and the situation will degrade, and everyone will be unhappy and there will be restlessness. And at that time, Kṛṣṇa comes. He says, yadā yadā hi dharmasya glānir bhavati (BG 4.7).

Kṛṣṇa has taken His incarnation in the form of Hare Kṛṣṇa mahā-mantra. So if people take to it, chanting Hare Kṛṣṇa mahā-mantra, the present situation of the world can be favorable for our living, and atmosphere will change. Therefore the Kṛṣṇa consciousness movement is meant for this purpose, to give people relief from all these burdens so that they can peacefully live, understand the value of life, and become spiritualized so they live peacefully in this life and go back to home, back to Godhead. That is the mission of the Kṛṣṇa consciousness movement.
