Bhuvaneshwari mantra and yantra.

Bhuvaneshwari - Means the Queen of the Universe, Maya, power of love,

peace within, as void. She is like the red rays of the rising sun, with the
moon as her diadem, and with three eyes, a smiling face, bestowing boons,
holding a goad, a noose and dispelling fears. On the right side of
Bhuvaneshvari, who in the heavens, on earth, and in the underworlds is
known as the Adya, worship Tryambaka.
The mantra is: Om Hreem Bhubaneswaraye Hreem Namah
