"Pregare per" --> "to pray for".
In your translation "la grande realtà " seems to be the direct object of the verb "to pray/pregare/precare"; instead, in Italian, it refers to the aim of the action.
I know it sounds quite weird... but I think it could be something like: "We have to learn to pray, to ask for the coming of the great reality, i.e. God".
So, maybe, we should put an "ad+accusative"?
What do you think, dear?
Hi, dear colleague!
Oh, I don't know why I typed "precare" instead of "precari"? Have you noticed? I was suggested by Italian too much I guess.
Hm, I don't know if we can say "precari ad magnam realitatem"
We can "precari ad deos", but "ad magnam realitatem"? "Precari is a verbum transitivum, so I'm not sure if any preposition is needed.
According to my English-Latin dictionary "pray for"= petere, precari.
Maybe this version would be less ambiguous:
"In hoc sensu petere nobis discendum est,petere magnam realitatem".
