In "Loka sahitya" (Folk Literature) Rabindranath focused the importance and vitality of folk literature--"As the root of a tree is deep within the soil and the top spread out towards the sky, so the everywhere the lower part literature is widely covered under the deep soil of motherland, and it is specially narrowing of own land and regional. That is enjoyable and accessible to the human folk of own country not for the outsiders. That what is universal is based on the foundations of the local - thus there is a relationship between the root and the top - between the local of literature and its universal counterpart.
