How it shows up
The fourth line lives within a web of relationships, so its values are constantly tested by the people around it. The person may achieve material success even where the rules around them are far from ideal. The decisive question is what they allow themselves on the way to the goal. Awareness of their principles protects both them and those who depend on them. An honest look at the compromises they make is the best prevention.
At its best
The capacity to keep one's strength even in surroundings with lower standards. Any selfishness stays short of the line where real harm to others begins.
The shadow
Disregard for values when energy is plentiful and inner guidance is thin. This leads to corruption and erodes the trust and protection a community relies on.
Exaltation and detriment
In the activation table the line is marked ▲ (exaltation) when it is activated by Saturn, and ▼ (detriment) when by Mars. Exaltation brings out the line at its best, detriment its shadow.
