"raghupati kīnhī bahut baṛāī" is Chaupai 12 of the Hanuman Chalisa, which Tulsidas wrote in Awadhi. It means: Rama, lord of the Raghus, praised you greatly: "You are as dear to me as my brother Bharata." At their first meeting in the Manas, Rama tells Hanuman he is twice as dear to him as Lakshmana.
रघुपति कीन्ही बहुत बड़ाई ।तुम मम प्रिय भरतहि सम भाई ॥raghupati kīnhī bahut baṛāītum mam priya bharatahi sam bhāī
Rama, lord of the Raghus, praised you greatly: "You are as dear to me as my brother Bharata."
