What can be done about my client’s basement mold problem? Will prayer work help to eliminate the mold?

You will be surprised to learn that prayer work can be effective for such needs, and your instinct to recommend this was not ill-founded or mere speculation, but an intuitive awareness this is so. And you can share our words with him also, to recommend he do this. This is a beautiful application of consciousness in partnership with the divine, to work on an environmental problem. And this is a nice illustration of what the divine human can do to protect themselves, and to enhance the quality of their life, by calling on the divine in partnership.
