We learn crucial life lessons from the Mahabharata, several of which are from Lord Krishna.
Before the start of the Kurukshetra war, Arjuna was in two minds about killing his relatives over a piece of land. As his closest ally, Lord Krishna stood up to motivate him and told him the truth of life, that it is important to perform our duty without expecting anything in return. Lord Krishna’s words motivated Arjuna to go ahead with his action, which eventually led to the Pandavas success.
Motivation is an important lesson from the Mahabharata because it shows us that when you are motivated you can do anything and achieve your goals.
