To Bharat I would yield my wife,
My realm and wealth, mine own dear life,
Unasked I fain would yield them all:
More gladly at my father’s call,
More gladly when the gift may free
His honour and bring joy to thee.
In plain words: Rama says he would gladly give Bharata everything, even his wife, kingdom, wealth and life, without being asked. He would give it even more gladly if it saves his father's honor and makes Kaikeyi happy.
