trust is the most important thing in horsemanship

When the horse knows that you will never hurt him or let anything hurt him he will not fear anything

Explaining real trust

There is a big difference between playing with you and trying to hurt you and bitting with out hitting before or after means he's just playing with you and having fun

Horses fear anything new to them because they think it will hurt them and their nature is to run away when they are afraid so to stop them from running away they must trust you and know that you will never hurt them or let anything hurt them and that will lead to real trust which will give you total control,so if there is no pain there will be no fear and when there is no fear they will not run away

Total control is not impossible if you really get real trust....

When they trust you they will not fear anything because they know that you will never hurt them or let anything hurt them...
