“Krushnam vande jagat gurum” means I bow to Krishna, the teacher of the world.
Shri Krishna is historical figure and the Purnaavtara (complete incarnation) who appeared in this world on 18th July, 3102 BC, in the last part of Dwapar Yuga of 28th Manyavantra (around 5122 years ago). He appeared before Ma Devaki as four armed Vishnu at mid-night, Sravani Krishna Astami. The Vishnu Purana stated that it was a dreadful night with heavy rain and violent wind. He was 8th incarnation (Avatar) of Vishnu Bhagwan. He lived and died for the fellow human beings. He shared the joys and sorrows of kings and commoners alike. Not only he transmitted the wisdom of Upanishads & Vedas in form of Bhagavad Gita, but His life was also lessons on bhakti yoga, karma yoga, jnana yoga and Raja Yoga. The four dimensional perspective of His personality has been attempted in this article.
No scripture could recount the entire life of Shri Krishna. It is told primarily through Srimad Bhagavatam, Garga Samhita, Visnu Purana, Brahmavaivarta Purana, Mahabharata, Harivamsa and several other puranas.
Why called as Purnaavtara (complete incarnation of the almighty):
Shri Krishna proclaimed himself as Almighty and liberated many during his lifetime. He performed several humanly impossible tasks, showed Virat form and extra-ordinary qualities.
Shri Krishna is a perfect personification of divinity. He was a revolutionary of his time. He accomplished the protection of feeble & gentle, destruction of evil-doers and installation dharma. He believed that whenever popular righteous is in opposition, one should follow the higher cause of dharma.
He is symbol of compassion, tenderness, love, destroyer of evil-doers, perfect in his different roles, man of wisdom and above all yogeshwar.
