The popularity of the romance following Nizami's version is also evident from the references to it in lyrical poetry and mystical mathnavis—before the appearance of Nizami's romance, there are just some allusions to Layla and Majnun in divans. The number and variety of anecdotes about the lovers also increased considerably from the twelfth century onwards. Mystics contrived many stories about Majnun to illustrate technical mystical concepts such as fanaa (annihilation), divānagi (love-madness), self-sacrifice, etc.
