Anointing Rituals and Higher Density Energy Flows
Anointing seems equivalent to all the other kinds of side flows that go up into the next higher density and then loop back down. Examples from image E, F and G use arms, snake, and long-neck-bird, to show these flow connections. Image A, B and C use water flow, from a side flow to a center flow symbol. Image D is pouring from a center symbol to a side flow person-symbol without an extra upward loop, so it's a little different than the rest.
It's still unclear to me why this ancient message is important. Maybe its about conservation of energy, what goes up must come down, first rule of thermodynamics (in a multi-density system), or maybe its showing us there are lots of ways that higher-density energy can come in and out of our tori. Feel free to insert words like divine and spirit into my post. These words may have had a broader meaning than we realize nowadays.
