"You see. The devil's weed is like that. She sneaks up on you like a woman. You are not even aware of it. All you care about is that she makes you feel good and powerful: the muscles swelling with vigour, the fistsitching, the soles of the feet burning to run somebody down. When a man knows her he really becomes full of cravings. My benefactor used to say that the devil's weed keeps men who wantpower, and gets rid of those who can't handle it. But power was more common then; it was sought more avidly. My benefactor was a powerful man, and according to what he told me, his benefactor, in turn, was even more given to the pursuit of power. But in those days there was good reason to be powerful."

"Do you think there is no reason for power nowadays?"

"Power is all right for you now. You are young. You are not an Indian. Perhaps the devil's weed would be in good hands. You seem to have liked it. It made you feel strong. I felt all that myself. And yet I didn't like it."

"Can you tell me why, don Juan?"

"I don't like its power! There is no use for it any more. In other times, like those my benefactor told me about, there was reason to seek power. Men performed phenomenal deeds, were admired for their strength and feared and respected for their knowledge. My benefactor told me stories of truly phenomenal deeds that were performed long, long ago. But now we, the Indians, do not seek that power any more. Nowadays, the Indians use the weed to rub themselves. They use the leaves and flowers for other matters; they even say it cures their boils.But they do not seek its power, a power that acts like a magnet, more potent and more dangerous to handle as the root goes deeper into the ground. When one arrives to a depth of four yards - and they say some people have -one finds the seat of permanent power, power without end. Very few humans have done this in the past, and nobody has done it today. I'm telling you, the power of the devil's weed is no longer needed by us, the Indians.Little by little, I think we have lost interest, and now power does not matter any more. I myself do not seek it,and yet at one time, when I was your age, I too felt its swelling inside me. I felt the way you did today, only five hundred times more strongly. I killed a man with a single blow of my arm. I could toss boulders, huge boulders not even twenty men could budge. Once I jumped so high I chopped the top leaves off the highest trees. But it was all for nothing! All I did was frighten the Indians - only the Indians. The rest who knew nothing about it did not believe it. They saw either a crazy Indian, or something moving at the top of the trees."

We were silent for a long time. I needed to say something.

"It was different when there were people in the world," he proceeded, "people who knew a man could become a mountain lion, or a bird, or that a man could simply fly. So I don't use the devil's weed any more. For what? To frighten the Indians? [Para que? Para asustar a los indios?]

"And I saw him sad, and a deep empathy filled me. I wanted to say something to him, even if it was a platitude.

"Perhaps, don Juan, that is the fate of all men who want to know."

"Perhaps," he said quietly.
