Ratri
The Night, daughter of the Sky and sister of Dawn, praised in one Rigveda hymn (10.127) as a bright, starlit goddess who looks out with many eyes, fills height and depth, drives off the darkness with her light and keeps the wolf and the thief away. The Atharvaveda adds four protective hymns. In the Puranas Brahma sends her into the unborn Parvati to make her dark, and she later comes out as the lion-riding Kaushiki or Ekanamsha; the Devi Mahatmya praises the Goddess as the Great Night.
