Sakura asks whether Collection of Light could be characterized as a "weaker" form of perfection than CONJUNCTION, OCCUPATION, MUTATION, or TRANSLATION.

It is an excellent question and gives me an opportunity to clarify something.

MAGISTER ANSWERS: No. It is as strong as TRANSLATION, I would say. TRANSLATION can involve a third-party or outside factor bringing about perfection of the matter. The only difference is that COLLECTION may also involve a change of circumstances BEFORE the third-party gets involved and perfects the matter.

I have added that fact to REFERENCE: COLLECTION OF LIGHT.
