One important image Rabindranath Tagore uses in the poem “I Cannot Remember My Mother” is the image of a tune. The child remembers hearing a tune the mother hummed while rocking his/her cradle. A second important image is the shiuli flowers, the official flower of West Bengal, India. The shiuli flower is also used to mark the arrival of the Goddess Durga. The child thinks of his/her mother in the temple when he/she smells the shiuli flowers. A third image is the sky and it reminds the child of his/her mother’s gaze.
