Abhimanyu was the son of Arjuna and Subhadra.When Subhadra was pregnant with Abhimanyu,Arjuna,one of the five Pandava brothers,decided to tell his wife about the Chakravyuh war technique.
Arjuna narrated to Subhadra how to break the Chakravyuh,a labyrinth formed by armed soldiers to trap the enemy,and enter it.Abhimanyu heard and memorized the entire process from inside Subhadra's womb.
But by the time Arjuna told her about coming out of Chakravyuh,Subhadra fell sleep.As a result,Abhimanyu learned only entering the labyrinth but couldn't know how to come out of it.Later in life,when young Abhimanyu fought in the great Kurukshetra Wear of Mahabharata,he had to confront of enemy's Chakravyuh formation.He could get into the formation ,but could not come out.
Abhimanyu took a chariot wheel and swung it around,fighting enemies unarmed.He did not give up easily and fought valiantly till his last breath.
Moral:Abhimanyu's talr teaches us to stay determined even when the situation is not in our favor.One must never give up,no matter how tough the going gets.
