The most important point, I think, would be to identify a specific focus before you start your journey. And your first specific focus should be to find your spirit animal. Repeat your intention (i.e., specific focus) three times--helps the brain lock in
-- then begin. I'm assuming you have a drum beat or regular rattle sound to help maintain your focus. Your animal will appear three times and will be friendly--you'll know. Your spirit animal will become your guide. You should never journey alone or without a purpose--it's kind of a waste of time and could be dangerous. Been there, done that, don't want the T-shirt! Note that your spirit animal may not show up the first time. Don't give up. Give yourself a time limit on initial journeys. Perhaps your animal wants to be sure you are sincere. Good luck!
