Weeping Trees on Tombstones as Energy Loop-Backs

From tombstones, like image A and B, I got scared that my understanding of fountains was missing the "loop-back" aspect. So I had another look. For a tombstone with weeping willow style trees, a message of energy going to heaven and then returning, seems comforting. But many of these weeping tree pictograms lack a barrier.

Some have it. On image B, the barrier is the brim of that container (below the lid). On image A, no clear barrier, but there are Thick and Thin leaves, the latter are likely to be higher-density energy returning. I'll need further examples to study, but I'm pretty sure the meaning is not about crying. Most of my fountains just look like torus shapes like image F and G, but some have barrier penetrations, going above clouds, on image D and E. ( Clouds are commonly the barrier to higher-density, symbolically). Image C's fountain seems to have several barrier penetrations, one at the zodiac ring (horizontal plane) and one at the eye-symbol. So I won't panic about fountains and weepy trees, there's still time to keep looking.
