The Destination

Revision

Under arch of brow
a world of geometry beckons:
within the heated expanding center
passions,
through the pigmented light
a soul,
in the focus
intellectual curiosity;
the beam,
love warm and illuminating.
 
A lighthouse on a craggy cliff
guides a ship to dock in the harbor
and I am home.

Original (original title, A Journey)

Through the arch of a brow
is a world of geometry:
in the heated expanding center
passions,
in the pigmented light
a soul,
in the focus
intellectual curiosity,
the beam
love warm and illuminating.
 
A lighthouse on a craggy cliff
guides a ship to dock in the harbor
and I am home.

I personally think a better way to write the first two lines is a compromise of your two versions:
Under the arch of the brow
is a world of geometry.

To my ears, that sounds a little better than either of the edits you have. But, of course, this is getting into personal preference.

As for the lighthouse metaphor, I too thought that the craggy cliff was a reference to the body. In this case, I was connecting it back to the first two lines and thinking the eyebrow was the craggy cliff. If you don't want to go that route, and use the lighthouse as a metaphor for getting through the tough times in life instead of a reference to the body, I'd consider replacing the craggy cliff and instead use a reference to stormy weather or fog. That, I think, would more clearly communicate the idea of rough times in life that you are being guided through by your beloved.
