KAFI (Arabic Qafi), literally stands for the leader, the enlightener, one who fulfils the need. In poetics it denotes the refrain in a song or hymn, and is also the title given to a poetic form in Arabic as well as in Indian literature. Guru Nanak was the first to use this poetic form in Punjabi literature, and this he was followed by several Sufi poets and others. Kafi has also been called a ragim and a metre (tatank), though opinion differs on this count.In the Sikh Scripture, Guru Granth Sahib, Kafis have not been collected under any one raga; they occur under ragas Asa, Tilang, Suhi and Maru.
Kanwal, Kesar Singh is a femous short story writer of this period who has pursued the same tendency of reforming certain evils of our society. By going through the stories of his collection Prem Dian Tahngha one feels that no doubt in his aim he is one with other short story writers of this transitional period, but in the execution of that aim he is more clear, realistic and impressive. His minute observation and realistic depiction of life, take him a step ahead of some of his contemporaries. His stories are also, in a way, indicative of the pure realistic delineation to which our short story was heading, though from the technique point of view they are not of a high order.
