Something answers when a man finishes what he set out to build and offers it upward in the right spirit. The fire comes after the prayer, not before. A person labors, sacrifices, completes the work in good faith. Only then does meaning descend and fill the structure he made. The house stood empty until the thing arrived that made it worth building.
You cannot summon that fire on command. It answers something offered honestly. Do the work first. Pour out your best without knowing what will come, and the finished offering becomes a vessel something higher can inhabit. The glory fills the house because the house was finished and the heart was open.
