- Though Pandavas are only five members and Kauravas are 100 members, the final victory is achieved by Pandavas. This is because of the help of Lord Krishna. This tells us that divine help is necessary for human being and good wins over evil.
- Dhrutrashtra was taught good advices by Lord Krishna, Vidura etc, but he didn’t care about them because of his mad love towards his sons. This teaches us that ignoring good advices can cause harm and destruction. This also shows how the mad love of parents can spoil their children.
- Bhagavad Gita was preached by Lord Krishna to Arjuna in the field of Kurukshetra. This preaching is of excellent value even in these modern days. According to Gita, man should do his duty and neither be happy with good result nor be unhappy with the bad result of that work. That means man should perform his duties carefully without bothering about the results.
- The life of Karna teaches us many lessons. Being a bosom friend of Duryodhana, Karna could advice him good or bad. But instead of doing that, he agreed with everything Duryodhana said, and at last he lost everything including his friend. This tells us that a person should not agree blindly with everything his friend says and he has to correct his friend if he goes in wrong direction. Karna also had the habit of donating anything he is asked. Due to this he lost all of his precious things, so while giving one must see the necessity of the receiver. Karna is one among the evil four (Duryodhana, Dussasana, Karna and Sakuni). Though Karna had all good qualities, he is considered evil because he agreed to everything whatever Duryodhana said. So mingling with bad people can damage your honor.
- Spare the rod, spoil the child. This is true. Bhishma, the eldest of Kaurava clan could set right his grand children. But instead of doing that he remained a mute observer. This led to the great destruction.
- Ekalavya was a tribal boy. He was very much interested in learning archery from Acharya Drona, but Drona refused to teach him because of his caste. Then he learned archery on his own by making the mud idol of Drona. This character preaches that concentration and sincerity can win anything.
There are many characters in Mahabharata and each character teaches us different lessons.
