Normally, a manifestation needed to be awakened using the specified technique. However, when Dyon first saw the technique's booklet, he was shocked when he saw that it was written by an RR Sapientia.
Why? Obviously because manifestations existed for as long as time became an entrenched concept. Wasn't it impossible for the Sapientia family to have existed since the dawn of time? So how could a member of their family be the originator of the technique?
The answer was obvious, there were an innumerable number of methods for awakening one's manifestation and that particular book was only a single method.
It seemed that the Soul Tome cleansing effect also had a secondary side-effect. By cleansing the soul, it also became clearer to its owner, thus making communicating with one's manifestation far easier. In fact, it became so easy that Donari awakened it instinctually.
