Fire event from page level to Component. Can it be done with a Raised Event?

I wish to fire an event into a component outside of the component (from the page level) but I have so far NOT been able to.

For example. On my page a wish to make the component appear (a success message with an animated check mark) and say something like “congratulations [[firstname]]” then animate the check mark after the message had finished fading.

I tried to use Raised events but these seem to work one way - from inside the component to the page level. I need to fire/trigger something the other way.
