The state of mind of a poet can be described as their mood. Mood refers to the emotional atmosphere that the poet creates through their words, and it is influenced by their thoughts, feelings, and experiences. A poet's state of mind can range from joyful and optimistic to melancholic and despairing, depending on their personal experiences and the subject matter they are writing about. The poet's mood can also affect the style and tone of their writing and the themes they explore, as it reflects their perspective on life and the world around them. Therefore, the mood of a poem is a crucial aspect of the poet's creative process and can greatly impact how the reader interprets and experiences their work.
