This is a very important pasuram.Even after waking up
        all from Nanda to Balarama,when Krishna does not open
        His lips,they realise their folly in not waking up
        first NAPPINNAI,the chief queen and Purushakara (recom-
        mending authority) during His sojourn in this world
        as Krishna.They do it in this verse.
        Nappinnai is Sri NEELA DEVI,the other two being SRI
        DEVI (Rukmini) and BHOO DEVI (Satyabhama).Nappinnai's
        name is not found  anywhere in the Puranas and in
        Sanskrit poems except in SRI YADAVABHYUDAYAM of Sri
        DESIKA,where she is referred to as Neela; and in the
        stotras of Sri KURATTAZHWAN.See also  the "Taniyan"
        of Sri Andal -"NEELA TUNGA..." by Sri PARASARA BHATTAR.
        As we are sinners and the Lord is known for His "Swaa-
        tantrya" (acting according to His own will),it is
        necessary to approach Him through somebody who is very
        near and dear to Him and whose advice is infallible.
        Hence Nappinnai's intervention is is essential.
        She is addressed as Nanda's daughter-in-law,because she
        thinks that that is what gives her prestige and status
        in society.Sita,when asked by Hanuman said," I'm the
        daughter-in-law of Dasaratha first,and then only the
        daughter of Janaka." So to an Indian woman Andal's
        exhortation is: "After marriage a girl should always
        prefer herself to be referred to as the daughter-in-
        law of her father-in-law; which means that the welfare
        of her husband's family should weigh more with her
        than that of the family of her origin.This attitude
        would enhance her own prestige and bring immense joy 
        to her own family."
        This pasuram was the special favourite of our Acharya
        Sri Ramanuja.He was in the habit reciting to himself
        Tiruppavai stanzas while he went for his Maadhukara
        Vritti (for collecting the alms the householders used
        to give) .Once just as he reached the door of his Guru's
        house he was meditating on this verse.While the last
        line " SEERAAR VALAI OLIPPA etc " was on his lips the
        door opened to the clinking of the bangles of the
        daughter of his guru.Sri Ramanuja thought that it was
        Nappinnai herself who opened the door and overwhelmed
        with jubilation promptly prostrated himself before her.
        The terrified girl ran to her father and narrated the
        incident.The guru   TIRUKKOTTIYUR NAMBI exclaimed,
        "Jiya! were you reciting UNDU MADAKALIRU ? "
        What an understanding between the Teacher and the
        taught ! May that relationship save us all!.
