In plain words
If I were someone who knew so great a reason, I would not have been grieving that darśan has not come. Then Hanumān spoke. You think of Rāma, but are you taking part in Rāma's work? Today we think of God, but do we take any part in God's work? Not only have I thought of Rāma; I have dedicated my life to Rāma's work. This is the qualification that made Rāma draw me close to Him. I have not studied any Veda, any Śāstra, any Upaniṣad, not one; I have not learnt them. "So, together with that thinking of Rāma, I have dedicated my life to Rāma's work," he said. Next Hanumān put a question. "Vibhīṣaṇa, have you seen Mother Sītā?" he asked. I have seen her, Hanumān! Then have you made any effort for Sītā's release? I have not. You keep thinking, "Rāma-bhakti, Rāma-bhakti." Rāma's wife Sītā suffers so many hardships, yet you have made no effort to bring her to Rāma's side. "Still, in this, the two of us are joined by a kind of friendship, a kind of harmony. You have seen the elder brother. I have seen the elder sister. So you show me the elder brother. I shall show you the elder sister," he said. Then both of us will have seen the sister and the brother. In this way the two came to an agreement.
On another occasion, talking with Hanumān, Vibhīṣaṇa says: "Hanumān, do you not know where I am? Like the tongue among teeth sharp as quivers of arrows, I stand among these cruel rākṣasas. I do not get even a good chance to think of Rāma." Students can clearly recognise how great Hanumān's intelligence was, how great this intelligence was that came from Rāma's grace. As soon as he heard these words, Hanumān says: "Vibhīṣaṇa! Do the teeth fall first? Does the tongue fall first? The teeth fall first; the tongue does not fall first. So you live thinking of Rāma among the rākṣasas, as though among teeth. The rākṣasas will fall first. You will be protected. You need not grieve over this." he said. Think how subtle Hanumān's nature is. That is why that Vibhīṣaṇa kept describing him as serene, virtuous, Hanumān. These serene qualities, the strength, all of it comes to us through Prema alone.
