The earth has got potency to produce wood, trees and plants, but there are some earthen plot of land, it is not producing anything, desert. It has got the potency. If you pour water, it has got the potency to produce wood, but, in that . . . similarly, the mode of ignorance, those living entities, those who are in the mode of ignorance, they cannot have any knowledge of the Absolute Truth. That's not possible.
Therefore it is gradual evolution, from mode of ignorance to mode of passion. And passion, there is little activity. Just like animal, they have got activity. Just like a dog, we have seen, in the beach and other places, running very swiftly here and there, but there is no meaning. A monkey is very active. You have not seen monkey in your country; in our country there are monkey, unnecessarily creating disturbance. But they are very active. But human being, they are not so active, but they have got brain, they're working with brain.
