Quote from : Lord Shiv & Family: In English Rhyme Book

Parvati has wrathful incarnations surely, As Durga, Kali, Shitala Devi, Tara, Chandi, She has benevolent forms like Katyayani, Kamalatmika, Bhuvaneshwari, Lalita, Gauri. Parvati as the Goddess of Power does be, Who source of all forms and of all beings be, In Her all the power but exists undoubtedly, And She who the destroys all fear clearly be. The apparent contradiction that Parvati be, The fair one, Gauri, and the dark one, Kali, Suggests the placid wife, can change fully, To her primal chaotic nature as powerful Kali.
