Infinite Banking

I have a whole life insurance and at the time I bought the policy, my agent explained that should I need cash in the future; I could easily borrow from it and pay it back with interest.  I didn't know that the process is called infinite banking.  It's when you are making your money grow through interests.  I have also heard about infinite banking but I thought it has something to do with banks.  It was only when I read a blog post about infinite banking that I was able to understand that the two are one and the same.   It's good that I learned something new and it's good that I know where to run should I need cash in the future.
