Durga and Kali — what's the difference?
Durga and Kali are both forms of the one Divine Mother (Devi). Durga is the Devi as the invincible warrior who rides a lion and slays Mahishasura; Kali is the Devi as the destroyer of ego and evil, dark and beyond form. In the Devi Mahatmya, Kali emerges from Durga's own brow — they are one Mother wearing the face the moment requires.
This is the question newcomers ask most often, and it deserves a proper answer rather than a shrug.
The short answer
They are the same Mother. They are not the same form.
Hinduism holds that the Divine is one, and that it appears in whatever form is needed. Devi — the Goddess — is the one Divine Mother. Durga, Kali, Parvati, Lakshmi, Saraswati and many others are her forms. Not rivals. Not a committee. One Mother, many faces.
How they differ
Durga is the Devi as the warrior queen. Riding a lion, many-armed, each hand holding a weapon given to her by a different god, she is beautiful and utterly unbeatable. Her great deed is slaying the buffalo-demon Mahishasura, whom no man or god could defeat. She is worshipped through Navratri — nine nights of the Mother.
Kali is the Devi as the destroyer of what must go. Dark, unadorned, beyond form and beyond fear. Where Durga is the ordered fury of a queen at war, Kali is what happens when the fury is no longer ordered — and needs not to be. She is worshipped at Kali Puja on Diwali night, and through Navratri too.
Parvati is the Devi as the gentle mother and consort of Shiva — the same power in its benign, domestic, loving aspect.
Lakshmi is the Devi as prosperity and auspiciousness. Saraswati is the Devi as knowledge, music and speech. Both stand on our altar beside Maa Kali.

Two forms, one Mother. The difference is in how she appears, not in who she is.
The scriptural moment that settles it
In the Devi Mahatmya, Durga faces the demons Shumbha and Nishumbha. As her anger rises to its height, Kali springs forth from Durga’s brow — black, gaunt, terrible.
Read that carefully. Kali is not summoned from elsewhere. She comes out of Durga. One goddess, showing the face the battle demands.
That is the Hindu answer in a single image: not two goddesses, but one Mother whose love is capable of becoming terrifying when her children need it to be.
Where our mandir stands
We are a Shakta temple — the tradition that worships God as Mother, and understands the Devi as ultimate reality itself (Adi Parashakti), not as anyone’s junior partner.
Our presiding Devi is Maa Kali, and beside her stands Maa Bhameshwari, venerated in the tradition of the Bham lineage as an avatar of Kali Mata. Maa Lakshmi and Maa Saraswati complete our main altar. During Navratri we worship the Mother in all her forms — because they were never really separate.
Meet them. All the murtis of our mandir are introduced here, or read more about Maa Kali and the Shakta tradition.
