He heard her speech with willing ear, He looked again upon the deer. Its lovely shape his breast beguiled Moved by the prayer of Janak’s child, And yielding for her pleasure’s sake, To Lakshmaṇ Ráma turned and spake:

In plain words: Rama listens to Sita, the daughter of King Janak, and looks at the deer again. Charmed by it and wanting to please her, he turns to speak to his brother Lakshman.
