Sarasvati, Lakshmi, Kali

Lalita or Tripurasundari is the 16th day or full moon, with her 15 digits. Each of the Nityas has a certain number of arms, the totality of arms (= rays) of the whole circle being 108. Because any unit of time is taken as a microcosm or parallel of any other valid unit, each of the fifteen Nityas thus has 1,440 breaths. This identity between space, time, Tripurasundari and the individual is elaborated at great length in the Tantraraja Tantra.
The Nityas are the vowels of the Sanskrit alphabet and are identical with both time and space. For example, if the number of tattvas or consonants (36) are multiplied by the 16 Nityas the number of letters is 576. The multiples of this number provide the number of years in the different Yugas. So the circle of the matrikas and the Nityas is identical with the sidereal zodiac as well as mantra
