In the beginning of Mahabharata war, Arjun was not in a mood to fight against his own family. Then Lord Krishna, being the chariot driver of Arjun explained the auspicious “Bhagavad Geeta”. Bhagavad Geeta describes the path towards “Moksha” (the immortal peace). He explained so beautifully the ways of performing duties without having any expectations. He explained the reality of our body and spirit. He explained that the spirit is a form of energy, which is immortal. Only the body dies, not the spirit. It is like changing clothes from old to a newer one.
In Bhagavad Geeta, Lord Krishna described how to control the mind. If a person controls its mind, then that person can achieve the greatest achievement of life. In Mahabharata war Lord Krishna did not even used a weapon. But still he was able to control each and every activity through his versatile clever attitude. He showed his complete “Vishwarupa” to Arjun after giving him super natural eyesight. Because no one is able to see the “Vishwarupa” of Lord Vishnu with normal eyes. Only because of Krishna, Pandavas won the great battle Mahabharata war and Dharma was established.
After Mahabharata war, Lord Krishna was cursed by “Gandhari” and he accepted it with a smile. In every situation, he was smiling. It explains that a person should remain cool in every situation of life and welcome it with a smile. Due to the curse of Gandhari, the whole kingdom of Krishna was destroyed at the end of Dwapar Yug and Dwarka was emerged in the ocean. Then Lord Krishna went to the forest and sat under a tree for rest. At that time most of his super natural power was lost as he saved the life of “Parikshit” in the womb of “Uttara” by sacrificing all the good deeds gained by him throughout his whole life. Mistaking Krishna for a deer, a hunter named as “Jara” shoots an arrow, which was penetrated in the foot of Lord Krishna. Lord Krishna forgave the hunter and died.
Hence, the whole life of Shree Krishna is a perfect guide for the nation as well as every individual to live life in an effective way. And he proved himself to be the complete incarnation of Lord Vishnu in all stages and he justified his name “Yogeswar Purusottam Shree Krishna” in all the stages of his life.
