We all learned a new word at Diocesan Convention: Pula.
Pula means "blessing" in Setswana, the language of Botswana.
It also means "rain" because rain is very scarce in Botswana, which is home to much of the KalahariDesert.
Pula, because it denotes value, is also the name of the currency of Botswana.
So there you have it: blessing, rain, money.
When you are welcoming an honored guest, or in celebration mode, or when the rain comes, you shout PULA!
