The concept of "Inner Gold" and the role of a "healer" are two powerful ideas that will most likely be useful to you if you're on a growth and healing journey, or care at all about self-reflection.
Gold & Shadow
Firstly, let's discuss the notion of Inner Gold. It's the idea that each of us harbors unique qualities, gifts, and light that align us with the divine - be it Universe, God, Spirit, Higher Self, our innate wisdom, etc. These terms can be used interchangeably to refer to the same spiritual source.
However, due to past wounds, traumas, or unhealed parts of ourselves, we sometimes fail to see our own Inner Gold. We might admire or even resent people who mirror qualities in us that we haven't fully recognized or embraced (remain in the shadow).
