Destiny and Love

Yesterday night I saw a movie named "My Sassy Girl". That was a really beautiful one.. More than the picture, the thing that attracted me was the script.. I should say.. Oh, dear!! Its really superb..

Towards the end of the movie there is a dialogue section which happens between the old man and Sassy(oops..Jordan). It goes like this :

Sassy: Well, if he and i were meant to be together i would have been healed by yesterday

Old Man: What kind of nonsense is that? Yesterday was one day ago, your healing was off by one day.

Sassy: One very important day.

Sassy: Destiny has spoken, and to search for him,will be like trying to shape and mould destiny and that just can't be a good idea.

Old Man: Just suppose that the shaping and moulding of destiny is in fact your destiny

Sassy: Huh, i never thought about it like that..

Old Man: I'll tell you what destiny means if you really want to know, that's the least i can do for letting me stare.

Sassy: What does it mean?

Old Man: Destiny is the bridge you build to the one you love.

Wow!! That was a superb line..

But later i started to think on that line, yup.. that line alone..

But was totally confused. How can destiny be equated to building a bridge?

I donno.. that sounds a bit confusing..

As far as i know.. at least experienced, Destiny is something which happens out of our knowledge.. or which happens without our intention..

but then this 'building bridge' and all.. cannot be a destiny.. it happens with our intention.. 

I get a really confused view on saying we build bridges when we call it destiny.
We usually use this kind of phrase when we need to achieve a goal.. establishing stepping stones to get to where we want to be, to fulfil our dream..our aim.

But using the word Destiny for it, gives me a bit of twisted feel ..

I donno whether i am really thinking on the line.. But still my enquiry on this topic will go on..
