Food, maybe? There are probably foods out there that supply spirit energy, just like there are some that carry demonic energy.

That, or necessity drives the need to develop new ways of obtaining spirit energy. In the really long RP, for example, they put blood from a donor through a burner, and the fumes created contained large ammounts of spirit energy. Those fumes are then directed to a face-mask to allow the patient to breathe them in, thus taking in the spirit energy. ( =w=)/
