Thanks so much Ms. Sue:)

You're welcome, Sara.

I'm not familiar with the term "Spirit-Power." It seems to be a combination of two words, "spirit" and "power," which individually have various meanings. "Spirit" can refer to a non-physical essence or energy, often associated with supernatural or ethereal beings. "Power" generally refers to the ability to exert control, influence, or force. In order to get a precise understanding of what "Spirit-Power" might mean in a specific context, it would be helpful to provide additional information or specify the context in which the term is being used.
