The propaganda of Śaṅkarācārya was mainly based on this understanding, that "We should not think that we are the products of this material nature." We are not products of material nature. It is by some accident, by freaks of nature, by misfortune or some way or other, we are now in contact with it. But actually I am spirit, Brahman. So that Brahman nature has to be invoked, has to be . . .
We are . . . actually, just like a diseased person, he has to be brought into the healthy condition of life, to cure the disease. So just a man, when he's diseased and when he's healthy, from external feature, the same. Just like I am now healthy. So my external feature—I have got two hands and two legs and face and so many things—the same body, when I am in the diseased condition, you'll find the same hands, the same legs and mouth and everything, but the condition is different. I'll speak something nonsense because the condition has changed in the diseased condition. Similarly, in our diseased condition . . . this material life is our diseased condition.
