Two characters symbolizing the beginning of the Turkish literature in Anatolia are Mevlana Celaleddin Rumi and Yunus Emre who lived in Karaman and who definitevely set the poetic language:

Soon after Rumi, Yunus Emre emerged as the most significant literary figure of the Turkish speaking world to spread the Sufi teachings by mystic poetry. For more than seven centuries, Yunus Emre and his poems have lived in the hearts of people. For him, the cause of dual existence is love. It is through love that the unity of Being can be reached because love is the cause and purpose of life on earth. The path leading to Unity passes through the heart.

I am not here on earth for strife,
Love is the mission of my life.
Hearts are the home of the loved one;
I came here to build each true heart.

The road leading to knowledge is the same as the road leading to knowledge of God which means attainment of self-knowledge. Self knowledge forms the basis of every science:

Science is to know knowledge
Knowledge is to know your Self.
If you don't know your Self,
Then what's the point of your studies?

The grave of Yunus Emre is in Sarikoy to the east of Eskisehir. Every year an International Yunus Emre Culture and Art Week is organized in Sarikoy, Eskisehir within the 1st quarter of May.
