Tantra, worship of Devi-Shakti is referred to as a Vidya. Of the
hundreds of tantrik practices, the worship of the ten major Devis
is called the Dasa Mahavidya. These major forms of the goddess
are described in the Todala Tantra. They are Kali, Tara, Maha
Tripura Sundari (or Shodasi-Sri Vidya), Bhuvaneshvari, Chinnamasta,
Bhairavi, Dhumavati, Bagalamukhi, Matangi, and Kamala. These ten
aspects of Shakti are the epitome of the entire creation. Chapter
10 also outlines their consorts, although Dhumavati, the widow
form, is not allocated a consort.
There are several "levels" at which these Devis can
be worshiped with the prescribed Mantra and Yantra. Like a simple
worship of the yantra with the mantra recitation, as a remedial
astrological measure, elaborate worship with all tantrak rituals
for attaining various siddhis associated with these tantras and
for spiritual salvation.
Successful sadhana of these Vidyas gives several boons to the
practitioner. The Tantrik-Yogi who has control over his senses
and positively inclined uses the boons to guide people and for
the benefit of mankind.
