Hey Vishal,
What I've observed is that it really isn't that hard to cross the A&P, and can oftentimes happen with little or not spiritual practice (though it can just as easily happen with a lot of spiritual practice). As Daniel often points out, if you are searching out spiritual information, going on retreats, in short are in some position of "seeking," that often means one has "insight disease" (i.e. has crossed the A&P). That said, knowing you are in dark night (whether you are or aren't) is kind of like the booby prive of meditation. It doesn't really help all that much to know that you have "insight disease". As Ken points out in the video interview you still have to go through it, and find a cure for what's ailing you. It often is like dying, as he points out, but it's also a process of re-birth. Good news / Bad news.
