It was possible that the poet’s brother who has staying in a different place, must have complained of sadness. The poet’s response to that was to invite him to ‘my garden’ where there was brightness forever. She deliberately used contrasting images of depression and joy from the nature to encourage and inspire her brother who was down with hopelessness. As against, silent, lonely fields, fading flowers and darkness she presented peaceful sky, bright sunshine, unfading flowers, buzzing bees, forests with evergreen leaves.
All these images represented the human feelings in two opposite worlds. The poet’s world might be an imaginary place but they could create positivity in a depressed mind.
