Akilandeshwari (Ambal) of Jambukeshwara
Paadal Petra Sthalangal are Shiva temples sung in the hymns of the 3 Tevaram saints — Tirugnana Sambandar, Tirunavukkaracar (Appar), and Sundaramurti (Sundarar). Composed 7th–9th c. CE, the Tevaram is the sacred geography of Tamil Shaivism and foundational to the Shaiva-Siddhanta philosophy.
Thiruvanaikka is one of very few temples where Ambal is the presiding deity and receives the madhyanika puja BEFORE Shiva. Akilandeshwari was originally so fierce that Adi Shankara installed tatangam (ear-studs) to pacify her; these are re-blessed every Sripuram Friday.
Daily 5-fold puja (ushat-kalam at dawn, kala-santi 6 AM, ucchikalam noon, sayaraksha dusk, ardha-jama 9 PM). Principal offerings: jala-abhisheka, panchamrita (milk/curd/ghee/honey/jaggery), vibhuti, bilva leaves.
Every Paadal Petra's sanctity rests on WHICH saint sang of it and HOW MANY pasurams. Tamil Shaiva tradition treats the Tevaram as Dravida Veda — equivalent in holiness to the Sanskrit Vedas.
