While many are speaking about the increase in the spiritual tourism at Kanyakumari after PMs visit, it must also be noted that the temple has some very important inscriptions which are critical from the TN history perspective.
Some of the pillars, six to be precise in the Mani Mandapa houses a very important inscription which helped researchers to deduce the Chola genealogy and some of the historical events in Chola dynasty.

The six pillars have 444 lines engraved in them of which 419 are in Sanskrit written in Grantha lipi, describing the Chola lineage right from Surya/Manu, Sangam period Cholas to later Cholas. The inscription belongs to Vira Rajendra Chola who ruled between 1063-70.

The lines are almost similar to what is mentioned in the Sarala copper plates grants of the same king. The inscription starts with two prayer slokas of Siva followed by a prayer sloka of Vishnu.
“Let Bhavanipati, who has crescent moon in his head, who playfully creates, protects and destroys the world, who is the leader of speech, bless you with abundance of wealth” says the first sloka.

The inscription also has incidents from Ramayana and prices Rama as a righteous King. Some of the key Chola historical events are also mentioned in this which includes Aditya killing Aparajita and took over the Pallava Kingdom.

This completes with a Tamil portion detailing about the grant Vira Rajendra Chola made. He had donated two villages for the daily offerings to the Kanyakumari Amman, which it calls as Kanniyapidariyar. Hope this gets preserved well as it is one of the key records of Chola.
