A blue lamp contains liquid fuel, which is drawn up a wick that represents the body.

A yellow letter Aleph, which stands for Light (Ohr in Hebrew), surrounds this wick and represents the dynamic interplay between matter (body) and energy (soul).

Two angels stand in the red flame of the soul and guard the spiritual ladder that leads up to the Infinite One.

There are many other Kabbalistic symbols hidden in this postcard (primary shapes, a heart, lungs, liver, tefilin, altars, Moses carrying the Tablets, and more). How many can you find?
