The first one (above) brings to mind wading (trance dancing) thru different energy states or dimensions. Perhaps it shows a blessing wave?
The second one (below) reminds me of the power of healing touch (such as Reiki).
And this final one (below) is a half-toned variation on the healing hand. The previous version makes me think of Aboriginal Dreamtime or perhaps Navajo "Hand Trembling Way," while this second variant definitely reminds me of "insect vision."
