These twelve names of goddess vrh are given in the seventeenth chapter of lalitopkhyna the narration about goddess lalit. This is a conversation between Lord Hayagreeva and sage Agastya, Hayagreeva teaches Agastya the twelve names of goddess vrh. These are called the secretive names of vrh as these names contain the key to understanding who vrh is.
The gods and goddesses standing in the sky praise her with these names, says the brahmanda purana.
All twelve names describe the attributes of goddess vrh, apart from that, some names also indicate various forms of goddess vrh. This hymn also acts as a great protective armour for those who chant it.
