It is never possible to know another person completely. If it is ever possible to know anyone at all, that is.
This is because people never open up completely. They will always have a secret which they cannot share with anyone. Anyone. This secret will be the true self of the person. However much one may deny this truth but as long as the secret remains undisclosable – at least to one person – so long the person will just be the secret that he holds.
Though this may appear as a very cynical view of people, it is never far from the truth. Having said that, it is not practical to reveal everything. It will get people into troubles; it may mar relationships; it may hurt others. I am also not propogating that people should open up fully. All that needs to be said is that people cannot be fully understood if they have secrets. And people represent their secrets more than what they disclose.
The quadrant ‘I know, Others don’t know’ of Johari’s window is always the most profound and the truest.
