Kannadasan, the esteemed Tamil poet and lyricist, holds a special place in the hearts of millions for his profound and evocative songs that have graced the silver screen for decades. Among his vast repertoire of timeless classics, one particular song stands out, not only for its lyrical beauty and captivating melody but also for the fascinating story behind its creation. The song, penned for a film featuring two of Tamil cinema's biggest stars, Kamal Haasan and Rajinikanth, earned Kannadasan a National Award, solidifying his legacy as a master of his craft.

Kannadasan, often called "Kaviarasu" (King of Poets), was known for his incredible ability to weave words into magic, crafting lyrics that resonated with audiences on a deeply emotional level. With over 5,000 lyrics, 6,000 poems, and 232 books to his name, he left an indelible mark on Tamil literature and cinema. His association with the music duo Viswanathan-Ramamoorthy produced numerous memorable songs. He was also a producer, actor, philanthropist, and editor.

The story goes that Kannadasan, in a state of near-sleep, penned the lyrics for this award-winning song. While the specific movie and song title are not mentioned in the prompt, the anecdote highlights Kannadasan's genius – his ability to create exceptional work even when not fully conscious. This speaks volumes about his deep understanding of language, rhythm, and the emotions he aimed to evoke through his writing.

In 1969, Kannadasan was the first recipient of the National Film Award for Best Lyrics for his work in the 1967 film Kuzhanthaikkaga. This groundbreaking achievement recognized the importance of lyrics in Indian cinema and paved the way for future lyricists to be acknowledged for their contributions.
