On the plaque next to the painting at the museum it said the painting was depicting the idea that desire is the force of life. Those who have strong desires are the ones who move things in the world

The desire, in order to be effective, must have two qualities. It has to have the magnitude, the power, the passion in order to have enough energy to have an impact. And it also has to have direction.

The second quality of direction is important but often overlooked. If you have a lot of passion, but you are not focused or directional or intentional, your passion will spread out in all directions and not really have a great impact in any one place.

Excess magnitude can compensate for lack of direction. If you have your desire has excess magnitude, then perhaps you can spread it to two or three or four different directions and still make a great impact in one of the directions. But if you try to spread to 50 or 70 or 100 different directions, you will have only a small amount of impact in any one directions.

Perhaps someone with greater magnitude of desire can have more impact in multiple directions. But it is best in order to have the most impact to have the greatest magnitude of desire and focus in only one direction. This is how you bring about the most change in the material world.
