A very common negative habit that some of us possess is blaming others when required, either in the family or at the workplace, to save face & gain temporary respect, even if it is at the expense of someone loosing face & being disrespected. It is a very common occurrence in offices when an issue arises between people, before the issue is taken up with the head of the particular department or the office, one of the two people involved in the conflict, who is more at fault, will present his case to the head in such a way so as to blame the other & to free himself & maintain his reputation in the office & find favor with the head.
Let us look it from a higher level. The person who blames is attached to an image of himself being as being extremely efficient & well-respected at the workplace, who never does anything wrong or incorrectly. He identifies with this image completely & because of that is very attached to it. In the above scenario, if he lets his mistake come out in the open, this internal image, which he carries, would get tarnished (harmed), something which he is in love with. So there is attachment & because of that there is fear of loss or harm to the object to which there is attachment, the image in this case. This image, which is so defined in spiritual language, is called reputation in common language. Also, there is attachment with an internal image of being more successful by getting a possible promotion & progressing at the workplace in the future. This image is also about to get damaged since the job might be lost or a promotion might be stopped. So there is attachment to this second image & fear of harm to this image also. To protect these two images, the person plays the blame game. The Law of Karma, though, does catch up sooner or later with such a person and with such behavior. Being honest may cause temporary harm to these two internal images or reputation as defined above, but one remains safe according to karmic principles in the long run & the temporary harm, if any, is undone & respect regained.
