If you mean Layla, she is a character in a story, Majnun and Layla, by Persia's leading medieval epic poet, Nizami. It is a romantic tragedy that might be compared to Romeo and Juliet. Here the two star-crossed lovers are Bedouins named Majnun and Layla. Majnun became crazed with love for his unattainable beloved, whose parents forced her to marry someone else. He wandered in the wilderness surrounded by wild animals. Both lovers tragically die at the end. The spiritual significance of the tale is that Majnun's self-forgetful love led him to love of God.
Eric Clapton used the name of this heroine in his classic rock song "Laylah" that he wrote about the woman he was in love with at the time.
