Lyric discussion by Sir_Larrikin 

I've heard about the star travel meaning for years; never thought to look at it from the angle of the Volunteers being soldiers... very cool interp. Of course, the "milky seas" is very descriptive of the stars in the sky - heading deeper into the Galactic Center.

The lines about writing letters in the sand, to mean man's impermanence, always gave me chills.

"Your mother's eyes in your eyes cry to me," could mean that's confronting his descendants, or else he's returned to find his wife dead, and he's talking to his daughter.

I also always loved the line, "Don't you hear my call though you're many years away." As if the space between them is a span of years, not miles. The location is the technical same, but time has pulled his wife away.
