The inductive power of linguistic signs of a poem is inspired from different kinds of literary techniques and arts which act as the source of inducting meaning. Such semiotic competence mostly used by poets in creating their literary works. Sohrab Sepehri is among those contemporary poets who gave profound semantic depth to his poems to make them more impressive by using natural elements as well as artifice inspired from his poetic authorities. To this end, the library provided us with the corpus found in Sepehri’s most important book entitled "Hasht Ketab" (Eight books) .To analyze the collected data descriptive –analytical method used. Theoretical framework of Saussure and Peirce’s semiotic notions employed to disclose the fact that the process of semantic creativity comes from the utilization of natural signs represented in the semantic layers of Sepehri’s poems. The results of the present research revealed that different elements of nature (Wind, water, soil, rain, plants, animals, …) frequently used by this poet can transfer moral values and peaceful symbiosis. To be more scrounger and active considered to be focal points learned by him from natural elements and he sees all of them as beautiful signs of God.
