I would like to know what " ford off " means..

It´s in the heavenletter # 4005...

In this paragraph...

There is the sense in which we could think of you as a wolf-child. You have an uncanny layer of you that has not been domesticated and for which you have no vocabulary. Sometimes it seems like a game you play where you ford off the truth that lies within you, some deeply buried, some closer to the surface. You go only so far and prevent yourself from going further. You fear to tread.

Thank you
