How it shows up
The expectation of a mentor is projected onto a fifth line, and it can offer practical knowledge that genuinely helps. It understands that a successful union naturally leads to separation over time: the student matures, and that does not harm the value of what they shared. Such people do not cling to their role and are glad when others become independent. Problems arise when the contribution becomes an end in itself and they cannot release those they guided.
At its best
The teacher whose contribution is a form of sharing that accepts limits. They pass on knowledge and let the student go once ready to move on. Their students stay grateful.
The shadow
The parent who cannot let a grown child go. They experience others' independence as a challenge to their authority and hold on to control. The bond turns sour.
Exaltation and detriment
In the activation table the line is marked ▲ (exaltation) when it is activated by Jupiter, and ▼ (detriment) when by Sun. Exaltation brings out the line at its best, detriment its shadow.
