Sun in the eighth house brings a person into territories where ordinary confidence no longer works: risk, crisis, other people's resources, power, debts, inheritance, intimacy, fear, dependence, survival, psychological depth, and contact with what cannot be fully controlled. This is not the easiest placement for the Sun, because the personality opens not through calm stability, but through tense transitions.
Such a person is often tested by circumstances. Where another person becomes lost, they may suddenly gather themselves, mobilize, and show their best qualities. This is why people with Sun in the eighth house are sometimes seen as lucky: they pass through dangerous or difficult situations and somehow come out dry. But this is not always easy luck. Often behind it stands an inner readiness to face what others turn away from.
