It seems to me that Buddhism, especially the Theravada branch of it, may have some especially useful insights to offer along these lines.  Buddhist Enlightenment (as well as I can express it within the limitations of my current understanding) is a state of getting beyond our own personal desires, and gratefully accepting life as it actually is.
 
This appears to fit remarkably well with the view of souls that I now hold—i.e., as beings that have shed all the physical equipment by which they might directly make things happen, and whose main interactions with our world seem to be offering helpful wisdom and guidance to those who need it.
