Even though Edwin is Candrasa and enters the level of the strongest wrena in Yamani, the ability to separate body and soul is not that easy for him to get. Since he found out how to get that ability from Dirga, he has tried it and thought that it might not take that long since he is a Candrasa.
But in fact, the time frame needed still couldn't be as short as he had expected. Even with such a high level of power, if he wasn't used to fasting and meditating for many years, he still couldn't get that power.
This also makes Edwin unable to see the soul forms of the humans who have managed to roam in Yamani or even on Earth. Dirga is the only Wrena who can do that, and he is finally able to observe everything about Berawa because of this special power.
