This romantic Tamil lyric is from the film Agni Natchathiram directed by Mani Ratnam, with music by Ilaiyaraaja. The line expresses how a single glance or word from a beloved can mean everything. 16 Vayathinile, Bharathi Kannama, and Kadal Pookal are Tamil films but this song is from Agni Natchathiram.
