Hindi: Ab pachtaye kya hot, jab chidiya chug gayi khet

Translation: Now what do you regret when the bird has devoured the field

What that means is that, why do you want to regret now, when the bird came and it already ate all of the seeds of your farm. It means why do you want to regret something that has already happened. Basically don’t regret what’s in the past and you should always concentrate on the present and the future, because regret doesn’t make our future life happier or more successful. I think this saying talks about seeds and stuff because India was a primarily agricultural economy and saying in India are related to the rural life.

What type of situations would you use that?

Like whenever people are bitching about other people, or saying a past situation was not nice or whatever. 

Thoughts: I think this is a great proverb for happiness. It shows that the past is done, and the only thing we have control over is the now. It is Hindi equivalent of the saying “no use in crying over spilled milk.”
