Once, Bheeshma approached sage Drona and requested him to teach the art of war to Pandavas and Kouravas .
Sage Drona graciously accepted the job. Though he was teaching all of them very well. Arjuna excelled others. There was a general complaint that Sage Drona was partial to Pandavas. One day Sage Drona called all the family members of Pandavas and Kauravas and told them, “Today, I am going to test the students. Please wait and see.” He chose two identical rooms and allocated one of them to Pandavas and the other to Kauravas. He also gave equal amount of money to them . He told them, “Please make use of the money and fill up the entire room. .
Kauravas went and purchased hay, sand, old articles etc. and filled up the entire room allocated to them. The room became dark. Nobody could even enter the room.
Whereas , Pandavas went to the shop and purchased beautiful lamps, oil and wick. They placed the lamps in different places of their room and lit them. The lamps were glowing beautifully and the entire room was filled with light .
The family members were asked to inspect the rooms and decide themselves who is wise. They understood the cleverness of Pandavas and appreciated them .
Pandavas spent the money cleverly, judiciously , usefully .
Use available resources cleverly, judiciously and usefully. Success and prosperity is certain.
