Meaning of Heartplace?

[Spartayu]

Hi mates! I know that perhaps the same question might had been asked before, or it maybe an outdated stuff to do to dig out old questions..

However, I'm still very confused by the real and actual meaning behind the song, "Heartplace". First, when I read through the first few parts of the lyrics, I could easily understood that it's about human freedom (or maybe not?). But this part really placed a stone on my path;

When I felt the warmth of someone I passed by
Tears welled in my eyes suddenly
It might be you, it might be that guy
Or that girl

Was it some kind of ballad instead of a song about freedom? Or was it some kind of song more about finding our right partner?

Additionally, I'm also curious as to the purpose of this song
