Poets use imagery to heighten the effect of the poem. They use similes, metaphors to produce word pictures in the minds of the readers. This poem is rich in such word pictures. The image of flowers waiting for rain, the cloud providing light shade for the leaves sleeping at noon are the word pictures in the first stanza. The dew drops wakening the buds, the picture of the cloud wielding the flail of lashing hail, the picture of a little baby, the clear blue sky without the clouds and the cloud gradually building up again are the other pictures that come to our mind when we read the poem.
