अपि स्वर्णमयी लङ्का न मे लक्ष्मण रोचते ।
जननी जन्मभूमिश्च स्वर्गादपि गरीयसी ।।
After defeating Ravana, and freeing Sita, Lord Rama established Vibhishana as the ruler of Lanka. Rama's younger brother, Lakshmana, requested him to stay for some more time in Lanka, as it was such a beautiful city.
Rama replied that he was not tempted to tarry there. He did not like (न मे रोचते) Lanka (लङ्का) , even though it was filled with gold (अपि स्वर्णमयी), and very wonderful.
In Rama's view, ones's mother and one's motherland (जननी जन्मभूमिश्च), were both superior to even heaven (स्वर्गादपि गरीयसी).
So how could a mere earthly city like Lanka keep him from returning to Ayodhya ?
The coat of arms of Nepal was changed in December, 2006, to include the flag of Nepal, Mount Everest, green hills, etc., plus a white silhouette in the shape of Nepal. The national motto of Nepal, though, written on the earlier coat of arms, was retained in the new one too.
It is-" जननी जन्मभूमिश्च स्वर्गादपि गरीयसी l "!
