The dhEvAram given to this world by chundhara mUrthi nAyanAr form part of the 7th thirumuRai. These hymns blessed by chundharar are also called as thiruppATTU. chundharar hold a very special relationship in the devotion to Lord shiva and so are the hymns sung by them which are the testimony of this strange but sincere devotion. As could be seen from the life of sundharar(1), he lived the material life but the focus of which was just and only just Lord shiva. Whether he wanted liberation or Grace of Lord to help the suffering people or as minor things as sandal paste and materials or even the girls he wanted to marry - his only hold was Lord shiva to get anything fulfilled. The worship of Him and His devotees were the only things his tongue sings. Very naturally these characters of this great devotee are well depicted through his wonderful padhikams.
Justifying the name vanRoNDar (harsh devotee), one finds the hymns in which he talks hard with the Lord Himself !! When that outpour of marvelous love takes the form of humbleness, he affirms, reaffirms, re-reaffirms that he is the slave only to that Marvelous Unique Lord shiva. The most important aspect of Sundharar's songs is the devotion and the humbleness to the devotees of the Crescent crowned Lord. While there are so many hymns hailing the great devotees of the Lord, the masterpiece of Sundharar is the thiruththoNDaththokai (2) which gave raise to the stories of the great devotees periya purANam (3).
One of the features of thiruppATTu is its simplicity. At times its is very simple flow of reading through, but still not compromising on the rhythm. There were 38,000 hymns composed by this devotee. But what is available to us now is only 100 padhikams (about 1,000 hymns) sang on 84 abodes. There is one paN (melody - rAga) called chen^thuruththi which is not found in the other thirumuRais.
