If you could only teach me one thing...

Isn't an 'adept' just good at penetrating the forgetting, and therefore the title would inherently describe a yellow-ray entity?

No adept is about balancing of the opposites fundamentally, but in terms of sts or sto polarity I believe it is neither blue or red but yellow. That is why Ra emphasises the techniques are similar for adepts of both polarities, the intent is what makes the difference.
