• Udit Udayagiri-manch par: "Udit" means risen, "Udayagiri" refers to the mountain from which the sun rises (eastern mountain), and "manch" means stage. So, this translates to "Upon the stage, which is like the rising mountain."
• Raghuvar bal-patang: "Raghuvar" is a name for Lord Rama, "bal" means child or young, and "patang" means the sun. So, this translates to "Rama, like the newly risen sun."
• Vikse sant-saroj sab: "Vikse" means bloomed, "sant" refers to saints, and "saroj" means lotus. So, this translates to "All the saints bloomed like lotuses."
• Harashe lochan-bhring: "Harashe" means rejoiced, "lochan" means eyes, and "bhring" means bumblebees. So, this translates to "Their eyes rejoiced like bumblebees."

Overall Meaning: Lord Rama appeared on the stage, which was likened to the Udayagiri mountain. He was like the newly risen sun. Seeing him, all the saints' faces bloomed like lotuses, and their eyes rejoiced like bumblebees. The verse describes the joyous atmosphere when Rama appeared before the saints.
