M T Vasudevan Nair

My entry into the world of Malayalam literature was through the masterful writings of M. T. Vasudevan Nair, whose passing today feels like a deeply personal loss. It was his novel Manju (Mist) that first drew me into this literary universe. The story, much like its title, was enveloped in an atmosphere of melancholy and mystery. It unraveled slowly, like mist clearing in the morning light, revealing truths that were profound yet heartbreakingly simple. The characters, their struggles, and their silences lingered in my mind long after I turned the last page. It was not just a novel; it was an experience. I returned to it over and over, each time discovering something new, as though the book was speaking directly to the depths of my soul. To this day, I cannot count how many times I have read Manju—it became, and remains, a companion to my thoughts. After Manju opened the door, M. T.’s other works beckoned me forward. I was soon engrossed in Nalukettu, a story that painted a vivid portra...

The story of Chinthavishtayaya Seetha

The poem is a retelling of the Ramayana from Sita's perspective, exploring her thoughts, feelings, and experiences. The poem begins with Sita's abduction by Ravana, the king of Lanka. As she is taken away from her husband Rama and the forest, Sita's mind is filled with thoughts of anxiety, fear, and uncertainty. As she is held captive in Ravana's palace, Sita's thoughts turn to her past life with Rama in the forest. She remembers the happy moments they shared, the love they had for each other, and the struggles they faced together. However, Sita's memories are also tinged with sadness and regret. She thinks about how she was forced to leave her comfortable life in Ayodhya and live in the forest, facing numerous challenges and hardships.
