A Raven totem means that you are often the human version of Mercury, delivering information to others. This may be something mundane like guidance in their protection or something deeply spiritual. Raven people often walk the line between the worlds, acting as a bridge (What Is My Spirit Animal).
People with the raven totem also seek stillness and quiet and often prefer it to the constant onslaught of chatter and noise in their daily lives. People with this totem are wise and will bring messages for others. As a result, the spirit world uses you as a bridge to the physical world to bring forth its directives. (Spirit Animals)
The Raven totem is a gatekeeper of knowledge, a keeper of secrets, and a protector of truth. An interesting note about this protection is that the raven guide often protects us from difficult truths, or inner demons. When faced with a challenge it will persist. It will approach the problem from many angles. (All Totems)
"With wings black as night, black as coal the Raven is a messenger from another world. When it makes it's presence known for you, you are about to receive secret knowledge, knowledge that will benefit you greatly particularly if you engage in the craft of magic or divination arts.". (Universe Of Symbolism)
