user8157: 'Reification' is making something real, bringing something into being or making something concrete.
The Pali suttas say about the relationship between consciousness and wisdom/enlightenment: 

Discernment (wisdom; panna) & consciousness are conjoined, friend, not disjoined. It's not possible, having separated them one from the
  other, to delineate the difference between them. For what one
  discerns, that one cognizes. What one cognizes, that one discerns. MN

Is the Enlightenment or Wisdom of a Buddha a Reification? 

user43: The Buddha attains the Truth through cessation of reification.
Reification is an important concept in (modern) Mahayana Buddhism. It refers to (samsaric) mind's tendency to assume something to be concrete and solid when in fact it's not. Reification is the opposite of the correct vision of Shunyata - the non-concrete nature of all phenomena.
Most if not all real life instances of Desire/Aversion/Confusion can be traced back to reification. One type of scenarios that can be explained in terms of reification is reading-in a concrete meaning into an abstract concept, and then applying that assumed meaning back to reality thereby overgeneralizing the observations. Some random examples that come to mind:

Assuming that "democracy" refers to some concrete ideology when in fact there is no single specific definition of it, and then passing judgements about people based on that assumption.
Fabricating an image of what "real love" must look like and then seeking to find it exactly like that in the real world. 
Assuming that Enlightenment or Nirvana refers to some concrete state that can be achieved "with a click".
Side taking in any social conflict based on a generalized ideological position.

Another class of reification scenarios do not start from a concept, but rather come from subconscious assigning of ontological status to one's own observations:

Overgeneralizing a person's physical appearance as "handsome" based on several characteristics that the observer finds matching one's preconception of beauty. Or even worse, finding those characteristics beautiful because they are assumed to be outward manifestations of inner qualities that the observer considers "good".
Solidifying the notions of "stupid" and "smart" as something concrete and then judging a person as one or the other based on very little evidence interpreted as "a sure mark".
Ego as a sum-total of one's opinions about oneself, one's social image,  one's values and beliefs, one's job and role - coalesced and generalized into a solid notion of "this is who I am".

(I will add more examples as I remember them)
In a way, all our (samsaric) experience is reification. The process of perceiving objects, events, places, space, time, arising and destruction of entities - is a process of constructing fabrications from observations and reifying them as something concrete and separate from everything else and from the observer.
The Buddha attains the Truth through cessation of reification.
