Vitality, recognition, becoming visible.
Your Sun line runs through the places on Earth where the Sun was directly overhead, or on the horizon, at the exact minute you were born. It is the strand of your chart tied to identity and life force.
The trip we would build
A visibility trip. Somewhere you arrive as a version of yourself with nothing to prove, with room in the itinerary for the thing you would normally talk yourself out of.
A Sun line is not a personality upgrade. It amplifies what is already there, including the ego. Go when you want to be seen, not when you want to hide.
It depends on the minute you were born, not your sign. Three short questions and we draw the map.
