I have been told from several different people that it is possible for one person to have multiple Besherts (divinely intended marriage partners, soulmates if you will) to choose from. He may only choose one at the end, but there are several possible options. A quick search online will bring you claims like, "it says that every person has 7 zivuggim", but no source to back it up.
This is usually told to people who have never been married, (which seems to indicate they are referring to the first marriage, and not to subsequent marriages).
Is this true? Is there a source for this statement? And if so, is it universally applicable, as everyone who quotes it seems to think, or is it limited (perhaps to a second marriage)?
