CC's explanation on seeing

[shamanka]

In order to manipulate and understand the emanations which arrive to our senses, sorcerers develop the power of their attention, sharpening it through discipline to exquisite levels, which allow them to transcend human limitations and to fulfill all the possibilities of perception. Their concentration is so intense that they can penetrate the thick armor of appearances, and expose the essence of things. Seers call that degree of increased awareness 'seeing.'
