Our approach to reconciliation:
James Gibson in an article about the truth and reconciliation movement in South Africa defines reconciliation in the following words. 

We at Sri Lanka Unites do not believe that reconciliation can be achieved over night. It is a process that will take a generation to implement with an authentic commitment and perseverance. 

“People of different ethnicities getting along better with each other that is, the decrease of ethnic animosities. This may mean that people come to interact with each other more (the breakdown of barriers across ethnic groups), communicate more in turn leading in to greater understanding and perhaps acceptance, resulting in the appreciation and exaltation of the value of ethnic diversity. It is this dimension of reconciliation – the extension of dignity and esteem to those of other races, ethnicities and cultures, through understanding trust and respect. - James Gibson
