16. Mahānityā (अः / aḥ)

JyothiViswanadham Yes, they are related to the expanding qualities of the 'five great elements.' It is a bit complicated and requires a solid understanding of how the tattvas unfold in reality according to the nondual Śaiva traditions. Unfortunately, the exact correlations between the tattvas (and their preceding tanmātra qualities) and the Nityākalā devīs are not given in the texts as far as I've seen, but the general idea is that the tattvas flow from one another and the previous tattvas are the cause of the following ones--gathering qualities as they 'cascade' throughout reality. As an example, concerning the five principal elements, the so-called lowest tattva, earth "pṛthvī" would contain all five qualities of the tanmātras. If I manage to find the exact correlations between the devīs and the qualities of the pañcamahābhūtas, I will let you know. Śrī gurubhyo namaḥ

Adikeshava

The tithis 15 are classified into 5 pancha boothas. That way the boothas or elements are mapped Tithi Devis inside the Shir Chakra.

Nanda, Bhadra, Jaya, Rikta and Poorna are mapped to Pratipat and so on.

And in turn Nanda etc are mapped to Pancha Boothas.

Saraswati

As per Shri Chakra's tithi Devis, each Devi return back to Surya, and all become one on Pournima. And they go away as waxing of Chandra starts.

So the naming is same from Amavasya and Pournima starting, as from Kameshwari.

In the temple of Lalitha Ambhika in ThiruMeeyachur, the above sequence is followed, and in the drawings of tithi Devi's also there.
