Info on Shamanic Totem Animals Wanted

Dear soul brothers and sisters,

I know there are a few of you out there who are versed in shamanic practices, and I would be very grateful if somebody could enlighten me as to the meaning of a particular totem animal: The Raven.
I have done a little bit of research on the internet but have come across some contradictory information, and I am not sure as to the solidity of some sources.
So I thought I would ask the best people for the job (you). :-)

With many, many thanks and a heartload of pure, unadulterated, mindless LOVE
