In the conditioned state we are identifying "I am American," "I am Indian," "I am human being," "I am this," "I am that," "I am white," "I am black." These are all designations. Actually, this is not self-realization. Self-realization is that "I am neither American nor Indian nor black nor white, nor anything. I am a spirit soul, part and parcel of the whole, Krsna." This is self-realization. So long it is not completely realized, so long we have got doubt, we have to make progress. And as soon as we come to the point and firmly convinced, that is self-realization.
