A traveler was passing through a desert on a hot day. He was tired, feeling thirsty and hungry. At least, he needed a shady spot to rest for a while. A big leafy tree came into view at some distance away. He felt glad and said to himself, “Had I water to drink, now.” Yes, he found a glass full of cold water on the ground right in front of him. Then, he wished, “Had I something to eat right here.” Immediately, a variety of dishes appeared before him. He was under the shade of Kalpa-Vriksha — a magical tree. Whoever was under it would have whatever he wished for!

The traveler enjoyed the delicious food. He felt drowsy. He wished for a nice bed. It was granted. He stretched himself comfortably on the soft mattress. He hoped that someone would massage (按摩) his feet. Yes, a young lady appeared. She started massaging his feet and legs.

He now started thinking differently. “How can things happen like this? Is it some kind of a trick played by a magical demon (魔鬼)?” he doubted. Oh, a true demon appeared in place of the nice lady! Within no time the demon started leaping at him, with his mouth wide open. The frightened traveler took to his heels and ran away.
