Baboon's express themselves freely and are associated with judgement. Baboon's are one of the very few animals who will take vengeance. Does it seem baboon is terrorising you? Where have you overstepped the bounds of the natural world?
Anger, lust, fear and all the emotions we tend to withhold are expressed by baboons. Are you withholding? Could more emotional freedom serve you?
When baboon appears to you take a look at what judgemnet is being reflected at you. If baboon is peaceful, you are judged as peaceful. If baboon is angry, where are you out of alignment?
