Can anyone provide a nice intuitive explanation for the main properties of homothetic vector fields? Alternatively, could anyone point me in the direct of a thorough reference?

There is nothing cooler than G. S. Hall's "Symmetries and curvature structure in general relativity". A wonderful book.
 
Many thanks, will grab it tomorrow from the library!
