Andalum Thiruppavaiyum. And apologize in advance for such a lengthy reply.
Kodai Nachiyar was adopted by Periazhwar(vishnu chitar) . Vishnu Chitar (from now onwards we’ll call him as Periazhwar only) wrote lot of Paasuram on Krishna & HIS leelas.
In our home (our means we Iyengars) we used to talk lot about Krishna . every little boy is Krishna only to Granparents isn’t it?
By this way she must have learnt about Krishna. This is mechanically analysis
we’ll analyze Kodai Nachair’s incarnation In terms of bakthi now.
After His Krishna incarnation Bagawan Vishnu on his return from bhoolokam enjoys in Paramapadam with niytya soories . Over come with remorse on looking at earth (Despite his GITA upadehsam no one follows it & do all paapam)where all atrocities take place he ask Devi MahaLakshmi to take an incarnation in earth to reiterate his GITA upadehsam .
She politely refused HIM saying that even when being with you during your incarnation I suffered a lot like vanavasam( forest living )& Agnipravesam etc,therefore swami, I’ll(MahaLakshmi) not take any more incarnations.
Bagawan then ask Bhudevi to perform this act. She (Bhooma Devi) immediately/ eagerly accepts the offer saying I’m waiting for this opportunity
. During His Varaha Incarnation, bagawan tells Three things to Bhooma Devi for the upliftment of HER(BhooDevi’s) subjects
Prostrate on HIS lotus feet & perform archana by offering fragrant flower.
Chant his Thirunamam Loudly( pl note this) this is for those who says so & so are not supposed to chant VSN etc, this is for them.
seek saranagati (surrender) on his lotus feet.
She took Andal incarnation to tell/show us about the varaha upadesham, appears in The Tulasi vanam of swami Periazhwar. She made two Garlands. Poomalai( flower garland) which she wears first & then give to VataPathra sayi( Perumal Ranga Mannar of sri villi puttur)& PaaMalai( poetry-rather divine poetry). Which she sung for HIM.
Thirupaavai form 3 parts.. The first Ten parts ( Paasuram-slokam) tells us to chant HIS nameThe second part tells us to offer prayer to HIS lotus feetThe final part tell us to surrender ourselves on his Thiruvadi(lotus feet).
Thirupaavai is not a simple verse. Its an yagnam. The yagnam performed by Andal from the Upadesham of Varaha Murthy during the start of this kaliyugam.
Whenever an yagnam(sacrifice) is performed, the Protasam( offering for the Yagnam) used to be kept in Kapaalam( a type of utensil-if I’m right its used to be made of wood) . This Thirupaavai’s (of Kodai Nachiyar) three parts (of each ten Paasuram) forms three Kapaalam .
during the performance of yagnam(sacrifice)Whenever this protasam -kapalam to be submitted to Agni it’s usually accompanied the chanting of perumal-Trivikramavataarm Thirunamam(name)
Andal chants about Trivikraman Thirunamam in each parts(above mentioned) in Thirupaavai.
1 .inPaasuram no(3) .. “Oongi ulagalanda uththaman per Paadi”.( pl see the meaning from stanza no 3 of Thirupaavai in Vadagalai Iyengar community{http://www.orkut.co.in/Main#CommMsgs.aspx?cmm=14784311&tid=2573452729859210658&na=3&nst=49&nid=14784311-2573452729859210658-5229429691472129323 }) this is from the first Ten Paasuram of Thirupaavai.
2. .inPaasuram no(17)”Ambara mudarauthongi ulagalanda” .( pl see the meaning from stanza no 17 of Thirupaavai in Vadagalai Iyengar community ) is from the second Ten Paasuram of Thirupaavai.
3. inPaasuram no(24)”Andrivulagam alandai adi potri” ”.( if god willing we’ll see the meaning of this stanza of Thirupaavai) is from the third Ten Paasuram of Thirupaavai
So It isn’t surprising that Andal being the Bhudevi incarnation & raised as the daughter of Periazhwar knows about lord Krishna, whose avataram(incarnation) took place in the previous yugam.
I do hope I’m not deviated from the subject
