Vision: Seeing or working a plow: you have not been productive enough in the past. Increasing your efforts, being persistent, and having patience—in spite of the hurdles in your way—is the way to reach your goals.
A broken plow: you want to start something new, but your plans will probably fail. Seeing someone else plowing: you are looking at a task and wonder if you should take it on. It could be profitable.
Depth Psychology: The plow is a challenge to “plow under” past experiences, injuries, insults, old behavior, and attitudes. This gives you a chance to change the old into something new for the future; the “soil” on which you grow and build a new life will be healthier. See Earth.... Dreamers Dictionary
