Objective: Love and mysticism are frequent themes of Persian literature that poets have addressed in different literary periods. Sadi is one of the poets whose divan is full of this theme and love and mystical themes along with its edges and the description of the lover and the beloved and their characteristics are abundantly expressed in his sonnets. Gul Mohammad Khan Zeib Magsi is one of the contemporary Baloch poets who has experimented on different subjects in his collection of poems called Khazineh al-Ashar and Zeib Nameh. In this article, the themes of love and mysticism in the poems of Sadi and this great contemporary poet are examined and compared. Zeib Magsi is a poet of the 14th century AH and is very far from Sadi's era. But he took advantage of the poets before him and in the book Khazine al-Ashaar, he wrote his poems with the guarantee of the sonnets of the previous poets. Therefore, the description of love, lover and beloved in his poetry is similar to that of classical poets and does not differ much. Like Sadi, he describes the lover as sad and lamenting, and the lover of his poetry is unfaithful and persevering, and the lover always lives in hijran. True love also has many manifestations in his poems, and in his mystic sonnets, he is the true beloved of God, and through the guidance of an elder, one can reach perfection. The comparison of the use of mystical terms of two poets shows the frequency of the themes of existence, dignity, aging and self-contradiction in Gul Mohammad's poetry, and the frequency of the themes of deterrence, discretion, submission and satisfaction in Sadi's poetry, which itself expresses the dominance of mystical love in Sadi's poetry Research method This research has been done in a descriptive-analytical way, in this way, by reading the poems of Saadi and Gul Mohammad Khan, the things that are related to love and themes related to it have been identified and classified and compared at the end, and the statistical results is provided. Results: According to the examined cases in the divan of Saadi and Zeib Magsi's poems, we find that the main theme of the poems of these two poets is love, its consequences and its sidelines, including true and spiritual love, which forms the form of mysticism, and earthly love and It is virtual. Saadi himself was influenced by previous poets and his ghazal is based on a lover who has existed in Persian ghazal for a long time and has external beauty, cruelty and unfaithfulness. His lover is incomparable but moody and evasive and his lover does not give up easily. This lover is present throughout the Persian romantic ghazal and no transformation can be seen in it. Accordingly, in the poetry of Gul Mohammad Khan Zeib Magsi, who follows the thoughts of prominent poets before him, a lot of attention has been paid to mystical and earthly love. The book Khazineh al-Ashar is based on the sonnets of Iraqi style poets There are common features in Zaib's poetry that raise the theme of love like others. He also has an unfaithful lover and is always in pain. Mystical love is expressed in many of his sonnets. Even though his poems were written in the contemporary period, his language is still related to the Khorasan and Iraqi periods and is consistent with his romantic and mystical themes, therefore, many similarities can be seen in comparison with Saadi's poetry. But it cannot be said that he definitely followed Saadi; Rather, his divan shows that he was familiar with classical poets and used the poetic thought of all of them and developed the themes by paying attention to the themes of the predecessors. Conclusions: The comparison of the poems of these two great poets shows that Saadi describes the lover and the beloved side by side, and as he describes the beauty and behavior of the beloved, he also considers the state of the lover and created a balance, but instead of describing the lover, Zeib Magsi He has connected the topic and expressed his wishes. Both poets have used imaginary images such as similes and metaphors in their descriptions. But apart from mystical love, comparing the most prominent and widely used mystical terms used in the poetry of Saadi and Zeib Magsi, it seems that Gul Mohammad Khan Zeib Magsi pays more attention to mystical elements such as the unity of existence, recourse to the elderly, survival and dignity. but Saadi spoke mostly to his friend and sought his pleasure and was powerless in front of him. In fact, Saadi's poetry has more romantic elements and Gul Mohammad's poetry is more mystical. In Zeib Moghsi's poetry, mysticism is mostly mixed with ethics and religion, and in Saadi's poetry, mysticism is mixed with love, and because of this opinion, we can distinguish between them.
