How to translate blessing
"Blessing" is a tricky word because it is not a concept that in-universe Mandos would understand the same way that many people on Earth understand it. By the "modern" era, which is what the Mando'a conlang was designed for, Mandos do not believe that gods have much of a hand in the affairs of mortals — assuming that an individual even believes in their existence. Thus, it's better to find a different way to express the same sentiment. Some suggestions:
dinuise: gifts
jatne dinuise: best gifts
jate balace: good opportunities
jatne balace: best opportunities
jate bane: good occurrences
jatne bane: best occurrences
(Ban is word derived from banar, "to happen.")
riyese: favors
jatne riyese: best favors
Or you could be specific, such as:
briikase: happiness
kot: strength
mirshko: courage
naak: peace
orilin: surplus, profit
waadas: wealth
