WARNING: Please listen to this warning before you proceed to call upon Kali. Kali is fierce. Meaning, when you use her mantra you are invoking a fierce energy. Her energy is not subtle. The results can be rather dramatic.
Kali, the dark mother of the Hindu pantheon is oft the most misunderstood Goddess in all human spiritual endeavor. Her images often depict her as being an evil and demonic force that few should ever dare call upon whilst others worship her as benign Goddess whom bestows blessings upon her supplicants. She is, in fact, both of these.
Kali will challenge the stuffiness and properness you have acquired in this life. She will challenge who you think you are. She will spit in your face, she will push your buttons and will humble you. She will make you face your demons. Cut away your pride. She would be the one to push you into the deep end of the pool so you can learn to swim. She will show you the futility of your overly valued words and notions of yourself to which we all idolatrously worship.
