Don't - I'd close it right away as a duplicate of FS#6 :-P

LOL ... well I considered changing this thread title to "soft shadows 
without area lights", because I wasn't able to blend the shadow on the 
base (subsurface) with the shadow on the ground plane (area light) ...

Just for the heck of it I ditched the area light from the back light 
(fill light never was an area light), and added subsurface to the ground 
plane. It /used/ to be a zero thickness box. The first run just sat 
there and crunched for what seemed too long before it started the 
preview, so I trimmed down the size of the box and gave it some 
thickness (same as base). Interesting how some of the filtered light 
from the stone made it into the subsurface on the base and ground plane 
(no photons)
