What the song is about
The singer wonders whether something good will happen. At first they don't know, then they think it is likely, and by the end they are completely sure. The song climbs a ladder of certainty, from maybe to undoubtedly, and ends with the feeling that it was meant to be.

Careful: lyric language
- "a certain mind" is poetic and made to fit the rhyme with find. In normal speech say from a little doubt to being certain.
- "the meaning is pure" is mostly there to rhyme with sure; it doesn't have a clear everyday meaning, so don't copy it.
- "I have a doubt" is used for the rhyme with out. More natural is I have some doubts or I'm not completely sure.
- "a certain truth": certain usually means "sure" here, but before a noun a certain can also mean "a particular" (a certain person). Context tells you which.
- "maybe it's a no" is informal but natural: a yes / a no means a yes or no answer.
