Annamacharya, The Saint-Composer composed 32,000 Sankeertanas (devotional songs) and dedicated them to Lord Venkateswar. His Son, Peda Tirumalacharya and Grandson, Chinatirumalacharya got the Sankeertanas of Annamacharya engraved on copper-plates and Treasured those Copper Plates in "Sankeertana Bhandaram" (a rock-built-cell at TIRUMALA temple). He is believed to have been the reincarnation of the precious sword of lord Vishnu (Nandakam). He is widely regarded as the Aṃdhra Pada kavitā Pitāmaha (grand old man of Telugu song-writing).
Annamacharya is said to have composed as many as 36,000 sankeertanas (songs) on Bhagwaan Govinda Venkateswara, of which only about 12,000 are available today. Annamacharyaconsidered his compositions as floral offerings to Bhagwaan Govinda. In the poems, he praises Venkateswara, describes his love for him, argues and quarrels with the Lord, confesses the devotee's failures and apprehensions, and surrenders himself to Venkateshwara. His songs are classified into the Adhyaatma (spiritual) and Sringaara (romantic) sankeertanas genres. His songs in the "Sringaara" genre worship Bhagwaan Venkateswara by describing his amorous and romantic adventures of Venkateswara and Alamel Manga, while others describe the Bhakti of his devotees.
In his later keertanas, he espouses subjects such as morality, dharma and righteousness. He was one of the first few who opposed the social stigma towards the untouchable castes in his era, with his sankeertanas explaining that the relationship between God and human is the same irrespective of the latters' color, caste and financial status, in beautiful yet powerful usage of words in his songs.
