In the context of the poem, "clear stream" represents a state of mental clarity, purity, and tranquility. It symbolizes the poet's aspiration for a mind free from fear, prejudice, and confusion. Just as a clear stream reflects the unadulterated beauty of nature, the poet desires a mind that is unclouded by negative thoughts and emotions, allowing for a deeper understanding and appreciation of the world around him.
Dreary desert
Conversely, "dreary desert" represents the arid and desolate state of the mind when it is plagued by fear and ignorance. It symbolizes the mental stagnation and limitations that fear imposes, preventing the individual from experiencing the richness and diversity of life. The poet yearns to escape this barren mental landscape and embark on a journey towards enlightenment and self-realization.
