“Heart, in his beauty’s garden” by Khatun and “Plant friendship’s tree” by Hafez both use the imagery of gardens and plant life to talk about relationships. Hafez discusses relations with friends more and how it can be just as pleasureful as being in love with a significant other. He uses the example of a tree to suggest friendship should grow like a tree. Khatun compares divine love to gardening. He uses metaphor to say that the roses (beauty) of his lover are gone and he is left with only thorns (pain).
I agree with you; in fact, both poems connect the idea of love and relationship in a very unique way. Hafez helped his followers understand the importance of human love that leads to the pure divine love. Both poet, Hafez and Jahan Khatun, used nature as a metaphor in order to prove their ideas of relationships.
