shes looking life from a positive side in this song... talking about going out into the real world 'its all ahead of you', 'its just the beginning', 'here comes the world' and how that experience is 'beautifully mysterious' and she says thankyou. maybe thankyou for being alive after all people who are alive have a 'light in their eyes' metaphorically...apposed to someone who isnt alive
