Hi everyone. I was hoping someone could give me some information about the translation of "Let it be" into sanskrit. Some people have told me that it would be Astu, and I've looked that up in a few spots and while it seems about right I've seen a few different definitions for it and just wanted to make sure it could mean what I had in mind. I am looking for the translation of the phrase "let it be" meaning 'to just let things happen as they will; to leave alone and let exist as is'. Does Astu work for this definition?

Thanks very much for any help!
