* Kali is Krishna revealed as dreadful Power and wrathful Love. She slays with her furious blows the self in body, life and mind in order to liberate it as spirit eternal.*

* Who can bear Kali rushing into the system in her fierce force and burning godhead? Only the man whom Krishna already possesses.* 

 * When will the world change into the model of heaven? When all mankind becomes boys and girls together with God revealed as Krishna and Kali, the happiest boy and strongest girl of the crowd, playing together in the gardens of Paradise. The Semitic Eden was well enough, but Adam and Eve were too grown up and its God Himself too old and stern and solemn for the offer of the Serpent to be resisted.*

*from 'Thoughts and Aphorisms' by Sri Aurobindo'

The Cosmic Dance (Dance of Krishna, Dance of Kali) 

Two measures are there of the cosmic dance.
    Always we hear the tread of Kali's feet
Measuring in rhythms of pain and grief and chance
    Life's game of hazard terrible and sweet.

The ordeal of the veiled Initiate,
    The hero soul at play with Death's embrace,
Wrestler in the dread gymnasium of Fate
    And sacrifice a lonely path to Grace,

Man's sorrows made a key to the Mysteries,
    Truth's narrow road out of Time's wastes of dream,
The soul's seven doors from Matter's tomb to rise,
    Are the common motives of her tragic theme.

But when shall Krishna's dance through Nature move,
His mask of sweetness, laughter, rapture, love?
