Krishna is an avatar of Vishnu (Christ) who was active in the Atlantean era. His story is told in the epic Mahabharata, which itself documents the wars between the solar and lunar races.
As a bodhisattva, and incarnation of Christ, his life story reflects his teachings, especially to provide examples for the average person to follow: that is why it is said:
"...he was an ideal son, an ideal brother, an ideal husband, an ideal friend and an ideal king. He can be taken to embody all the highest ideals of man. He led the ideal life of a householder in order to teach humanity.
Krishna was a man of action. He was a history-maker and righter of wrongs. He stood for justice and righteousness. His policy was to defend the oppressed from the oppressor. He was a master of superphysical powers. He was a man of knowledge and a world-teacher. He was a divine musician. He was the Lord of Yogis. He was the friend of Arjuna and Uddhava. His immortal teachings to Arjuna and Uddhava on Yoga, Bhakti and Jnana are unique. Even now they stir the hearts of the readers and goad them on the spiritual path and instil peace into their hearts.
Lord Krishna was the greatest Karma Yogin of all time. He held up the torch of wisdom. He was an embodiment of wisdom and selfless action. He combined in his life all that is best, highest, purest and the most beautiful, sublime and grand in heaven and earth. He was all love for the cowherd-boys, cows, and the Gopis. He was the friend and benefactor of the poor and the helpless. He was a versatile genius.
Krishna was a thunderbolt to the wrestlers assembled in the arena of Kamsa and yet he had the softest heart among men. He was Yama, Deathcome, unto Kamsa, Cupid unto the Gopis, the object of constant meditation for Yogins and devotees, the form of bliss and beatitude to the sages, and a child to his parents. He was Cupid unto Cupid himself (Sakshat Manmatha-Manmatha).
Lord Krishna was an embodiment of humility, though He was the Lord of the universe. He became the charioteer of Arjuna. He took upon Himself the duty of washing the feet of the visitors, voluntarily, at the time of the Rajasuya Yajna performed by Yudhishthira.
A paragon of purity and knowledge, Krishna embodied the gnostic ideal: a perfect human being living for the sake of others. He said:
"Humility, unpretentiousness, non-injury, forgiveness, uprightness, service of the teacher, purity, steadfastness, self-control, indifference to the objects of the senses, absence of egoism, perception of or reflection over the evil in birth, death, old age, sickness and pain, non-attachment, non-identification of Self with child, wife, home and the rest, constant even-mindedness on the attainment of the desirable and the undesirable, unswerving devotion unto Me [Christ] by the Yoga of non-separation, resort to solitary places, distaste for the society of people, constancy in Self-knowledge, perception of the end of true knowledge – this is declared to be Knowledge [gnosis / jnana / da'ath], and what is opposite to it is ignorance.” -Krishna, Bhagavad-gita
"The grand edifice of the ethics of his Gospel has been built on the eternal corner-stones of (1) Immortality of the Soul, (2) Immanence of God, (3) Impermanence of the world and (4) Immediacy of liberation. Because these truths are universal, the ethics of his Gospel also have universal application." - Swami Sivananda
