CHINNAMASTA SAADHANA

Her left foot forward in battle, she holds her severed head and a knife. Naked,
she drinks voluptuously the stream of the blood nectar flowing from her
beheaded body. The jewel on her forehead is tied with a serpent. She has
three eyes. Her breasts are adorned with lotuses. Inclined towards lust, she sits
erect above the god of love, who shows signs of lustfulness. She looks like the
red China rose. – Chinnamasta Tantra
Her mantra as per Mantra Mahodadhi is:
Om Shrim Hreem Hreem Aim Vajra Vairochaniye Shrim Hreem Hreem Phat
Svaha
It yields all desired benefits quickly.
