According to a legend, Goddess Kalratri demolished the demon Raktabeej. It is believed that it is only Goddess Kalratri who could slay the extreme torment of devil Raktabeej. No one was able to kill Raktabeej as even one drop of his scattered blood used to form another embodiment of Raktabeej and the scattered blood produced other billions of Raktabeej. Maa Durga incarnated herself in Kalaratri and kept a Patra (vessel) to keep and imbibe entire blood of Raktabeej. Her severe violent appearance while destroying Raktabeej and other demons hugely petrified all organisms of the world. But still, she is a kind Goddess for her great devotees.
The Devi Kalratri is worshipped with the chant of following Mantra:
या देवी सर्वभूतेषु माँ कालरात्रि रूपेण संस्थिता।
नमस्तस्यै नमस्तस्यै नमस्तस्यै नमो नम:।।
