I am familiar with some of the Bhakti Parampara Poet-saints from Western and Northen part of India and their works. Some of them are -:
Saint Dyaneshwar - commentary on Shree Bhagavad Gita (Dyneshwari, Bhavarthdeepika)
Saint Tukaram - Abhanga , Kirtan (community-oriented group singing and dancing form of Bhakti)
Saint Eknath - Eknathi Bhagvat.
Saint Namdev - Abhangas , Bhajans.
Saint Muktabai - Preachings to Saint Changdev.
Saint Ramdas- Shri Manāche Shloka, advises to mind about ethical behaviour and love for God.
Saint Tulsidas - Shree Ramacharta Manas.
Saint Meerabai- Bajan.
Saint Kabir- Kabir -Dohe.
These Saints are Representing Bhakti Parampara Or Bhakti Tradiation.
But I don't know much about Similar Bhakti Parampara Saints from South India region i.e., Namely from the States Kerala , Karnataka , Tamil Nadu , Andhra Pradesh
So I want to know more about some of the Saints who are associated with Bhakti Parampara or Bhakti Tradiation. Preferably from 12th century to 16th Century and about their literary works.
Note - You can give answer state wise also.
