The Kali Mantra as given in the Mantra Mahodadhi is:
"Kreem Kreem Kreem Hum Hum Hreem Hreem Dakshine Kaalika Kreem Kreem Kreem Hum Hum Hreem Hreem Swaha"
It bestows the eight supernatural powers.
The Kali Tantra gives details of the puja of Kalika:-
"Now I speak of the ritual injunction which is the all-nectar-giver of the Devi. Doing this, a person becomes like Bhairava.
"Now I speak of the ritual injunction which is the all-nectar-giver of the Devi. Doing this, a person becomes like Bhairava.
"Firstly, I speak of yantra, the knowing of which conquers death. At first draw a triangle. Outside, draw another. Then draw three more triangles. "Draw a circle and then a beautiful lotus. Then draw another circle and then a bhupura with four lines and four doors. This is how the cakra should be drawn.
"Worship the guru line, the six limbs, and the dikpalas (The eight, or according to some, ten guardians of the directions, ed.). Then the mantrin should place his head at the feet of the guru.
"O dearest one, after worshipping the pedestal, set down the offering. Place the mantra in the six limbs. Then, within the heart lotus, the ultimate Kala blossoms.
"Place her in the centre of the yantra by invoking her (via the breath). After meditating on the great goddess, dedicate the ritual offerings. Bow to Mahadevi and then worship the surrounding deities".
"Worship Kali, Kapalini, Kulla, Kurukulla, Virodhini, Vipracitta in the six angles. Then Ugra, Ugraprabha, Dipta in the middle. Then Nila, Ghana and Balaka in the inner angle. Then Matra, Mudra and Mita within this triangle, and then the very dusky one holding the sword, adorned with human skulls, with her left hand showing the threatening mudra and having a pure smile".
"Worship the eight mothers Brahmi, Narayani, Maheshvari, Chamunda,Kaumari, Aparajita, Varahi and Narasimhi.
"In equal shares, give these devis animal sacrifice and worship them, smearing them with scent and offering incense and flame. After doing the puja, worship using the root mantra.
"Give food and so forth to the Devi again and again. The sadhaka should offer flame ten times. So also he should offer flower with mantra according to the rules of ritual.
"After meditating on Devi, recite the mantra 1,008 times. The fruit of reciting, which is light, place in the hands of the Devi.
"Then, placing the flower on the head, do prostration. With supreme devotion, then rub out (the yantra)."
