The twelfth chapter of the Chandi Path (more fully called the Devi Mahatmayam or Durga Saptashapti) elucidates the many benefits deriving from the joy of celebrating the Great Goddess in her form of Durga. Holding that Devi in your heart and approaching her with love, she naturally bestows her grace and blessings. Let the Goddess herself be your guide and guru, inviting her into your heart.
It also may be used to consecrate and activate mantras that may need to be “woken up” or blessed by the Goddess herself. Be certain that you approach her with love and a pure motivation, and that your use of the mantra is in accord with True Will. In this day and age, when self proclaimed gurus abound and the vidya is becoming increasingly popular and diffused from the point of origin (the Goddess herself!), it certainly does not hurt to reconnect to the source behind the mantra, and allow that great Shakti to irradiate it with life, love, and power.
Recite the 12th chapter, asking for the blessings of Devi to use the mantra you wish to activate. Then give a round of the mantra (or more) with your mala or rosary. This simple act may be elaborated on greatly, but the essence is to connect with her and receive the blessings and empowerment of the mantra.
Those who prefer to love her under the name of Nuit may achieve a similar result by reciting the first chapter of Liber AL vel Legis, asking for the blessings of Nuit and giving a round of the mantra in love of her.
