The description says it heals difficult aspects of a chart. To me (and with the caveat that I honestly don’t know), that suggests it doesn’t so much change the chart as it helps you to deal with and use the difficult aspects of your chart more helpfully.
For most example, a square can be considered a difficult aspect because the energies are running at odds with one another. Those energies, though, can be used to our benefit. The tense energy of a square can be very motivating. It sounds like this field would help us find that motivating energy instead of the explosive energy that some people do with a square, you see?
