An Excerpt of the section "Theories Regarding the Oibrí and its potential functions" from the Leabhar na Sochraide
Our collective belief agrees strongly that the Oibrí’s very tangible kinesthetic presence to the individual implies a flexibility. It should be possible to make accurate observations in regards to its properties and character without the need for the opening of one of our sisters. Such a process is slow, but is most certainly the calling put before us by Aoire Sléibhe. From his slumber he must smile at our pursuit.
When a Sochraide Rugadhian comes of age they must decide what path they desire in life. Depending on what they choose to pursue, they may require the permanent altering of their Oibrí. By default they are capable of great Meyda-work, but if the research and creation of new Workings, perfection of Meyda-circles, or enchanting routes do not interest her she may instead follow through with An Lasc. A highly complex Medya-circle is drawn by one or more Sochraide, the Sochraide currently coming of age stands in its center, and the circle is then activated. It flashes a bright white, and the deed is done. Within the Sochraide a difference can be felt, and with guidance from fellow Sochraide and the Leabhar na Sochraide a new Rugadh may now be created.
