While the melody sounds celebratory, the context is deeply heartbreaking. It is sung by a lover who is watching the love of his life marry someone else.
May no sorrow ever come near you.May your lover always be yours by fate.May you keep lighting the lamps of happiness.May you keep decorating your beautiful new life. Verse 3: The Bittersweet Farewell
Or more formally:
"Congratulations to you on this wedding of yours."
"Mubarak ho! Here's to a marriage filled with endless joy, unwavering support, and boundless love." Final Thoughts
To fully appreciate the translation, it helps to understand the traditional concepts embedded in the lyrics:
Make your own / Accept them
Congratulations / Greetings
