Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Upon reaching Ayodhya, Lord Ramacandra heard that in His absence His brother Bharata was eating barley cooked in the urine of a cow, covering His body with the bark of trees, wearing matted locks of hair, and lying on a mattress of kusa. The most merciful Lord very much lamented this.
