‘The poetry of earth’ is not made of words. What is it made of, as suggested in the poem?
'The poetry of earth' is not made of words, but of the song and the rhythm produced by grasshoppers and crickets in various seasons. The music of the nature never loses its charm even with changing seasons. Summer and winter are the toughest seasons of the year. In summer it is extremely hot and in winter it is very cold. So in these two seasons there are rare songs of joy and music on earth. But here the poet points to the poetry of earth during summer and winter. In summer, the grasshopper seems to be excitedly hopping around, tirelessly, while even in lonely and dark winter nights, one can identify the shrill voice with which the insect cricket sings.
