Tamil Works on Vedanta

Although Vedic religion and its tenets find their place in the oldest extant Tamil literature, exclusive Vedanta works saw the light only 700-800 years before. The Vidyaranya swami inspired his disciples to write in the local languages so that the common man is not deprived of the lofty ideals of Vedanta just because of his ignorance of the divine tongue.
Vedic culture did not believe in direct scriptural education. The knowledge dissemination is achieved by motivating the expected behaviour through practice. Infact this is the reason why an average Indian is spiritual in outlook however quite likely he is religiously uneducated. This becomes the strength and the weakness of the Vedic Dharma at the same time.
Tamil language is rich in Vedanta literature. A sadhaka need not curse himself for his Samskrit illiteracy. He can know and practice Vedanta through Tamil only with little or no knowledge of Samskrit.
The following works may be of great help.

Vedanta

Vedanta refers to the advanced exposition of Vedas (Uttara Mimamsa). It is based on the Upanishads (primarily the principal 10 upanishads). The three canons (Prastana Traya) are the Upanishads, Brahma Sutra and Bhagavad Gita. It speaks about the triad Jagath, Jiva and Isvara. The Mandukya Karika says that soul is the witness for the three other states of consciousness - Jagratha, Swapna and Sushupti. The thought of Advaita inherent in Vedanta was explicitly exposed and epitomized by Adi Sankara. He wrote commentary on the three canons. He wrote the preliminary texts for the study of Advaita as a discipline. He is believed to have written many devotional hymns in praise of major Gods and Goddesses of Vedic/Hindu pantheon. After Sankara, the disciples and others who belonged to the lineage wrote various commentaries and original works and contributed to the literature of Advaita.

Tiruppukazh An Oracle Unparallel

Tiruppukazh - Glory of God. is the collection of hymns by the great saint Sri. Arunagirinathar. He wrote eight other works collectively called as Madanai - Chest Jewel which includes Tiruppukazh too. Madani comprises Thiruppukazh, Thiruvakuppu, Kanthar Alankaram, Kanthar Anthathi, Kanthar Anuputhi, Vel Viruttam, Mayil Viruttam, Seval Viruttam and ThiruezhukuRRirukkai.

Origin: Sri. Arunagirinathar hails from Tiruvannamalai, the famous temple town of South India. He practiced devotion to Lord Muruga. He started composing the Tiruppukazh songs after being blessed with the first word of the first song by Muruga Himself.

Goal and Efficacy of Isai Vazhipatu

Isai Vazhipatu is the rendering of Thiruppukazh and other songs of Sri.Arunagirinathar in the lines of Sri.A.S.Raghavan Guruji and followed by his disciples under the banner of Thiruppukazh Anbargal.
About hundred years before Thiruppukazh chanting was systematized and popularized by Sri. Vallimalai Svamikal. Although swamikal's disciplic succession still engage in Thiruppukazh singing, the authenticity of the rendering as a musical tradition got lost in time and also due to discord of the different disciple groups of svamikal. Sri. Guruji was solely inspired by Senthil Andavan (presiding deity of Thiruchendur Temple) to set to tunes the songs of Arunagirinathar. He started teaching the songs to the like minded friends and unconsciously he became the epicenter of the global spiritual movement Thiruppukazh Anbargal. He with his example revived, renewed and revamped the interest in the Holy songs and devotion to Lord Muruga through its soulful rendering.
