Bhutanese anthem lyrics (English translation)
In the Kingdom of Druk, where cypresses grow,
Refuge of the glorious monastic and civil traditions,
The King of Druk, precious sovereign,
His being is eternal, his reign prosperous,
The enlightenment teachings thrive and flourish,
May the sun of peace and happiness shine upon the people!
