Muthu Kumar had this knack of injecting the exact emotions which he wanted to convey in the very subtlest form. The great thing about this is that he does it with every emotion that exists.

He can make a guy who hasn’t felt what is love in his whole life feel the scars of a breakup. He can also put his hand around us and tell us “It’s okay” each and every time we need it. ‘Oru Naalil Vaalkai’ song in Pudhupettai is the song for eternity, arguably the best song written in tamil cinema ever.
There is this quote from Bruce Lee. “Be water, my friend. Be shapeless and formless. You put it into a cup, it becomes the cup. You put it into a teapot, it becomes a teapot. Be Water, my friend.”
Na. muthu Kumar lived like water and vaporized very soon. But we can feel his moisture that he had left with us for our lifetime. Remembering the legend on his birthday.
