Nammazhwar refers to Manikkunram, while Bhootattazhwar refers to Thanjai. Thirumangaiazhwar refers to Thanjai Maamanaikkoyil, and Manikunram. These temples are located in the outskirts of Thanjavur (the ancient Chola capital - known for its architectural masterpiece - The Brihadeeswarar Temple) in a suburb by name Vennatrankarai.
