Self Justification – sign of ego

Yes – self-justification [in a quarrel] keeps the thing going because it gives a mental support. Self-justification is always a sign of ego and ignorance. When one has a wider consciousness, one knows that each one has his own way of looking at things and finds in that way his own justification, so that both parties in a quarrel believe themselves to be in the right. It is only when one looks from above in a consciousness clear of ego that one sees all sides of a thing and also their real truth.
