In the ancient world the bull was a symbol of strength and power. Every culture in the ancient world was connected to bull worship in one way or another. Many people would seek the bull deity for divine blessings, whether for rich crops and a fertile harvest or for victory in battles.
A bull represents power, authority or brute strength. Being white indicates purity or singularity of purpose. Depending on what your bull was doing this could be something you need to do yourself, if it was passive it could be a call to take the bull by the horns and just do it. (whatever IT is)
