One day the topic discussed in the royal court of Krishnadevaraya was intelligence. The king kept talking about his courtiers’ intelligence. Some of the courtiers were very jealous of Tenali Raman and hence they told the king that they were very intelligent and clever but they didn’t get a chance to show their intelligence because of Tenali Raman.
King Krishnadevaraya did give a thought to this issue. He decided to do something about it in order to ensure a harmonious environment in his court. He turned to Lord Vishnu for guidance. His attention diverted to the incense stick burning in front of the god. The lighted incense stick was spreading scented smoke in the room.
All of a sudden, the king got an idea. He said to his courtiers, “I think you are right. You don’t get to prove your superiority because of Tenali Raman but you will get a chance to prove your superiority in the court. You can participate in a content for the same and thus you can get a chance to prove your extra intelligence and cleverness.”
He further told Tenali Raman, “Tenali, you are not allowed to speak or do anything in that contest.” This made all the courtiers who were jealous of Tenali very happy. Finally, they were getting an opportunity to impress the king with their intelligence.
The king said to all courtiers, “As you all can see the smoke coming from the incense stick. Bring me the smoke of the lighted incense stick of the length of one yard. The one who manages to do this will be declared as the most intelligent man in my court. He will also be declared as cleverer than Tenali Raman.”
The courtiers were shocked after hearing the king. They said, “What is the king saying? How is this possible? How can anyone measure smoke?” The king saw their surprised faces. He said, “You all wanted to prove your intelligence to me so this is to test your intelligence. I know some of you are capable of solving this so do it.”
The courtiers thought that somehow, they had to find some solution to this. Some tried to measure the smoke that was coming out of the lighted incense stick but in vain. Whenever they tried to measure, the smoke would disperse in wavy moments. Many of the courtiers kept trying various ways to measure the smoke till evening but nothing happened.
King Krishnadevaraya silently smiled at their futile efforts. Finally, the courtiers got tired after numerous efforts. One of them said to the king, “Your majesty, it is impossible to measure the smoke and to bring it in one yard length. I am sure even Tenali Raman cannot do it. Tell him to do it but I am sure he will fail this task too like us and thus he shouldn’t be given more importance henceforth.” All the courtiers agreed with him.
The king said, “Okay, I will tell Tenali to accomplish this task. If he succeeds this then we have to declare him the most clever and intelligent person.” All the courtiers agreed.
King Krishnadevaraya turned to Tenali Raman, “Are you ready to accept this challenge?” Tenali Raman stood up from his seat and came forward. He bowed to the king and said, “Yes sir, I want to try doing it with your permission.”
King Krishnadevaraya smiled, “Alright, you can proceed.” Tenali Raman called one of his servants and gave him some instructions in a low voice. The servant nodded and went away. He came back in a few minutes with a glass tube in his hands. The glass tube was sealed at one end and open from another. The glass tube measured one yard.
There was a pin drop silence in the court now. Everybody was eager to what Tenali Raman would do next. They didn’t want to miss any detail about how Tenali tried to accomplish this impossible task.
Tenali Raman went near the lighted incense stick. He held the open end of the glass in such a way that the rising smoke started filling the glass tube. Within a few moments, the glass tube was completely filled with smoke. Tenali Raman closed the open end of the glass tube with a cloth tightly.
Tenali then came to the king and handed him the glass tube saying, “Here is your smoke my Lord. This measures one yard. You can measure this with a ruler if you like.”
All the courtiers were shocked by what Tenali had done. King Krishnadevaraya smilingly praised Tenali Raman. He turned to the courtiers and said, “Now you all have to accept that Tenali Raman is the cleverest of all."
