The River Ganges or Gaṅgā - XIV

Goddess Kālī was very dark. Once she was in the company of beautiful, lovely, and fair complexioned heavenly nymphs and Lord Śiva jested about her dark complexion. Kālī felt insulted and became very distressed at Śiva's remarks. She practiced penance for one hundred years in the Himālayas and Śiva was forced to come and placate her anger. Kālī asked the boon of having a fair complexion and Śiva directed her to have a bath in the heavenly Gaṅgā.

Kālī took a bath in the river Gaṅgā, and became as fair as lightning. From then onwards, Kālī came to be known as Vidyut-Gauri.
