And when our woodland life is o’er, And we enjoy our realm once more, The wondrous animal will grace The chambers of my dwelling-place, And a dear treasure will it be To Bharat and the queens and me, And all with rapture and amaze Upon its heavenly form will gaze.

In plain words: Sita imagines that after their forest exile ends and they return to rule, the deer will decorate her home. She says it will delight Bharata, the queens and herself.
