Noticing Road Signs

From the Osho Zen Tarot, the Knight of Rainbows (Pentacles); from the A'HA Oracle, the Caduceus:

          The tortoise seems a perfect symbol for the Knight of Pentacles - he's moving and making progress, but he's not in a hurry. He is mindful of what is pleasant, unpleasant or simply dull. Nothing escapes his attention, because he takes the time to look at it all. Rarely does he find himself surprised, because he's noticed all the road signs along the way already. This Knight knows that no matter what one is creating, being attentive and aware can catch many problems before they become insurmountable.
          The "snake on a stick" symbol has been around for a long time. The Greek and Roman gods (Hermes and Mercury) had the caduceus; as messenger gods of commerce and negotiation, they represented balanced exchange and reciprocity. Nurses in the U.S. use it as a symbol for their profession, mistakenly confusing it up with the Rod of Asclepius (Asclepius was a Greek healer whose staff had one snake and no wings). The Hebrew Bible tells the story of Moses making a bronze snake and putting it on a pole, so that anyone bitten by a serpent would live (Numbers 21:9). All of these similar symbols have a theme: mutual and harmonious interconnection as well as healing and wellness. Yet none of these results are really possible without the mindfulness of the Knight.

Patterns and Changes

From the Osho Zen Tarot, Change (Wheel of Fortune); from the A'HA Oracle, "Caduceus:"

In the cosmos, a wheel spins; the lightning bolts that crackle around the center represent change. But the Taoist symbol in the middle suggests these revolutions are what keep things in balance: the seasons, sunrise and sunset, the cycles of the moon, life and death. Padma's commentary in her companion book states that if I am alert, I will see patterns that repeat over and over in my life as this wheel turns. Are these habits beneficial or detrimental? If I am mindful and aware, I can discern which are not constructive and choose to change them.
The caduceus was a staff carried by Mercury/Hermes, the god of transitions and boundaries. He was a messenger of the gods and a guide of the dead. Here in North America, his staff is often confused with the Rod of Asclepius, and thus it is sometimes considered a symbol of healing. These two cards combined seem to imply a change in the way I communicate with people. If I want that modification to be a healing, healthy one, I will need to pay attention to how I listen and speak to others.
