What do you know about Kali? What do you want to know?
A lot. I've experienced her love before when I was a Shakta. She's very beautiful and will hold your hand through struggles when you're ready. She prefers her devotees approach her as a child approaches their mother. She can be very tender. But she is very intense. She is viewed as black or dark blue and nude because this is a metaphor for eternity and the infinite. She's clad in the infinite.
Now she does have a more frightening aspect, which is rather vampiric. This is because she not only birthes the Cosmos, but she will eventually devour it in the great dissolution that is part of the eternal cycle of things. All things return to the Void from which all potential springs. This is scary to some, but it is just Nature and needs to be accepted. She has a lot of death aspects, being Time itself but saves her devotees through empowerment. She will help you see through illusion to the truth beyond, being the ruler of Maya.
I always loved this song:
"Maha Kali, dark mother dance for me
Let the purity of your nakedness awaken me
Yours are the fires of deliverance which shall bring me bliss
Yours is the cruel sword which shall set my spirit free
Devourer of life and death who rule beyond time
In thy name I shall fulfil my destiny divine
Maha Kali, formless one, destroyer of illusion
Your songs forever sung, the tunes of dissolution
Kalika, black tongue of fire, embrace me
Make me one with your power for all eternity
Awaken within me the reflection of your flame
Kiss me with your bloody lips and drive me insane
Jai Kalika! Jai Kali!
Make me one with your power for all eternity
Maha Kali come to me
Smashana Kali, I burn myself for thee
I cut my own throat in obscene ecstasy
I make love to abominations, embrace pain and misery
Until my heart becomes the burning ground and Kali comes to me
O dark mother, hear me calling thee
Mahapralaya, bring to me
Through all illusions I shall see
I shall cremate this world and set my essence free
Jai Kalika! Jai Kali!
Without fear I will dance with death and misery
Maha Kali, come to me
"O Kali, thou art fond of cremation grounds
So I have turned my heart into one, that thou may dance there unceasingly
O mother, I have no other fond desire in my heart
Fire of a funeral pyre is burning there."
[Female voice:]
Jai Maha Kali, Jai Ma Kalika
Jai Maha Kali, Jai Ma Kalika
Kali Mata, namo nama
Kali Mata, namo nama
Jai Kalika! Jai Kali!
At your left hand for endless victory
Maha Kali, come to me
Jai Kalika! Jai Kali!
Mahapralaya will set our spirits free
Maha Kali, come to me"
