What does motive energy mean?

When one's motive is outside of self, that is apart from greed and sense gain, and when his aim is toward some work of value to his race instead of toward some benefit—or accumulation for himself, he cannot escape success because it follows inevitably, but the moment the motive energy is degraded and its intentive force points, ever so slightly, toward money—or fame—or any other sort of personal possession, the work itself becomes degraded—or lacking in magnetic power.
