How does the 9th lord work in Mula Nakshatra?

If the 9th lord is the Sun and it's placed in Mula Nakshatra, does that mean a person's luck comes only after major setbacks and life lessons? Or can it indicate weak luck altogether?

I've read that Mula tends to uproot things to reveal the truth underneath, so I'm wondering how that plays out for the 9th house themes of luck, faith, mentors, and life direction.

Would love to hear your thoughts or experiences.
