Meaning for some lines in Arputha Leelaigalai - MKT film song

[HarishankarK]

I am giving lyrics for the song below.
Movie: sivakami
MD: KVM
Lyrics: Papanasam Sivan
Cast: MKT

aRputha leelaigaLai yaar aRivaar
akilaaNda naayakane harane undran
aRputha......

chithparane sivane unadhadiyaar
sey pizhaigaL poRutharuLum enadhaiyane
thiru abayavara kaiyane un
aRputha........

paattil aasaiyaal andru paravai manai
thoodhu nadandhavaa viRagu sumandhavaa
maattudaiyaay thillai kaattinile aruL
aattudaiyaay thalai Ottudaiyaay unnaik
kaatti maRaippaai ennai aatti alaippaai empi-
raatiyudane vaattamaRa inbam oottuvaai thunbam Ottuvaai undran
aRputha leelaigaLai.............

I need the meaning of the charanam lines. I think there is reference to some stories/thiruvilayadal/leelaigal here in the charanam. But dunno which ones. Could anyone please give the meaning of the charnam lines? Thank you so much

[Suryaprakash]

paattil aasaiyaal andru paravai manai
thoodhu nadandhavaa
Refers to the story of Sundarmoorthy Nayanar. "(Sundararin) paattil aasaiyaal anru Paravaiyaarin manai thoodu nadandavaa" addressing ShivaperumAn.

viRagu sumandhavaa - from Banabhadrar story in which the Lord assumes the disguise of woodcutter.

maattudaiyaay - with Rishabha vAhana
thillai kaattinile
aruL aattudaiyaay - refers to goat headed Daksha
thalai Ottudaiyaay - kAbali
(All of the above addressing the Lord)

unnaikkaatti maRaippaai ennai aatti alaippaai
(direct meaning and contextual in film, probably)
empiraatiyudane (with Ambal as consort) vaattamaRa (dispel my weariness)

inbam oottuvaai thunbam Ottuvaai undran
aRputha leelaigaLai.............( direct meaning)

Thank you very much Surya ji for the meanings. Now I will check in Google and read these stories.
May I request if you can include this song in your repertoire. It will be spellbinding in your voice.
