Lacan’s Lack/ Loss of object/ Real

The moment the child looks into the mirror, the child experiences him as a subject and others are all objects. The beliefs freezes that once he believed his mother breast, feces, loved dolls etc etc.. are one and the same. 

Now, the child finds the above missing part of him as “Loss of Object” and it gets permanently registered as ‘Lack’ in all forms of his future life. 
 
The lack is nothing but the absence of his mother’s breast, loved dolls, which are no more part of him are just separate or alien and stand as an object. (Before the above stand as an subject now it becomes object.)
 
The child understood someone castrated those once believed as subjects. The search is on to fulfill the ‘lack’ but the lack, ie. the loss of object will never ever be part of him till death
 
What is Lacan’s ‘Real’? 
Loss of object = Real. The child once grown up try to reach in all form, to reach the missing ‘lack’ (loss of object) in everything he encounters but the expereince will never equals the ‘Real’ (i.e. to his previous loss). 
 
Something happens good coz of castration is he was pushed to another platform, that is he is fit to live in the society. His cultural identity is only depend on such castration. 
 
Lacan says, the child is lost-the-object but find him as a subject, a kind of individuation happens after the Mirror Stage.
