Wait for right time

Time is always good but when right times comes  everything become right. Lord Krishna tried to make all understand that if we want favourable outcomes then we should wait for right time. 

During the battle of

 Mahabharat when Krishna observed that Guru Drona was proving himself great warrior and was becoming big hurdle in the winning of Pandavas, then Krishna told Arjuna  kill Guru Drona, but Arjuna did not want to kill his guru. 

Then Krisna tricked Drona by instructing Yudhishthir to announce that Ashwatthama had been killed, that was Elephant. 

When Yudhishthir announced about the death of Aswathama the Elephant, but at the same time Krishna blew  a conch shell and because of the sound of conch shell Guru Drona couldn't hear elephant and he thought his son Aswathama had been killed, so the Guru Drona became so sad and left arms and then  Dhrishtadyumna killed Guru Drona. 

By this incident we can learn about action and right time,. If action is taken on right time  then there is possibility of getting the result in our favour.
