It's knowing how to manage a person or situation once you open up a 'dark' area; I'd prefer the terminology that an area is 'dark' is rather referred to as something you're simply conditioned to (or suppressed/repressed) - it's underneath your conscious level, as otherwise it would leave you less able to function in day-to-day life.
Practicing meditation is a kin to understanding oneself.
"I found it easier than many to accept the epistemological notions of the world internal and external as dependent concepts enforced by ignorance and perceptual challenges."
