Thunchaththu Ramanujan is considered the father of Malayalam literature. The Adhyathma Ramayana in Sanskrit was written by Veda Vyasa. Adhyatma Ramayana is the Malayalam version of the Ramayana, written in the early 17th century by Thunchaththu Ramanujan Ezhuthachan. It is considered to be a classic of Malayalam literature. Ezhuthachan described it in kilippattu (bird song) format. The Adhyatma Ramayana represents the spiritual context of the story of Lord Rama.

The design significance lies in the representation of the story of Rama in the Adhyatma Ramayana. The text transforms mundane activities into spiritual symbols, elevating the narrative to a transcendent level. By mapping the attributes of Rama to metaphysical reality, the design aims to guide and instruct spiritual seekers. The Adhyatma Ramayana serves as a ready source of instruction and influenced subsequent works, such as the popular Ramcharitmanas by Tulsidas.
