Krishna is the Lord of Light.
His Light brings compassion and love.
He is the eighth avatar of Vishnu the Preserver.
When the Earth is in darkness, chaos, and evil Vishnu manifests on Earth as an avatar.
The most recent avatar is the Buddha - the ninth avatar of Vishnu.
The Buddha brings enlightenment.
One more avatar remains in this cycle of life - Kalki who sits on a white horse with a blazing sword - this manifestation of Light will appear when the Earth is in chaos, persecution, and evil.
Kalki bears a striking resemblance to the rider on a white horse in the Christian Bible's final Book of Revelation.
Madam Blavatsky claimed that this derives from the Hindu prophesy.
But I do not subscribe to the theology of violent suppression of evil.
Jesus is the Light of the World.
And Jesus himself prohibited violence.
"'You have heard that it was said: "An eye for an eye and a tooth for a tooth." But I say to you, Do not resist an evildoer. But if anyone strikes you on the right cheek, turn the other also.'" Matthew 5:38,39 (NRSV)
In my experience God - the author of the Light - is non-violent.
And the Light is all about the development of the heart - mercy, compassion, forgiveness, and love.
So do not expect a violent agent to reverse our descent into darkness and evil.
Corruption, violence, and evil are caused by fear.
When the Light comes we see that there is nothing to fear from God.
With this evil ends and we are free.
