Why are the clouds called brothers in coromandel fishers?

In the poem "Coromandel Fishers" by Sarojini Naidu, the clouds are referred to as "brothers" to evoke a sense of kinship and harmony between nature and the fishermen. This personification emphasizes the unity and camaraderie among elements of the natural world, suggesting that the clouds, like the fishermen, share a common purpose in their connection to the sea. The imagery reinforces themes of companionship and the cyclical relationship between humans and their environment.
