Without the knowledge of the Self, you will not be able to see your own faults, because you have the belief: 'I am Chandubhai. I have no faults and I am a 'goody-two-shoe'. When you acquire Self-Realization, you are no longer partial towards your mind, speech or body. And it is this very impartiality that allows you to see your own faults. When you find your own fault; when you see the faults that you make in each and every second; you are aware of when they happen and where they happen, you have become fully Enlightened Self. You become impartial after this Gnan, because this Gnan gives you the understanding that you are not Chandubhai, the relative self, but you are in fact Shuddhatma (the pure Self). You can only become impartial after you attain this separation from the relative.
You can say that you have accomplished your work when you no longer see the slightest fault in others, and you see all your own faults. Before this, you believed: 'This is who I am' and so you were partial towards your relative self. Now that you have become impartial, you have begun to see your own faults. Now your focus is directed inwards towards the relative self, and therefore you do not see other people's faults. Having begun to see your own faults, this Gnan will progress and yield its fruits for you. In this innocent world, where no one is at fault, how can we blame anyone? As long as there are faults, the ego is at play, and as long as the ego is involved, none of one's faults will be erased. Unless all the faults are destroyed, the ego cannot be destroyed. You have to erase your faults to the point where your ego is destroyed.
*Chandubhai = Whenever Dadashri uses the name 'Chandulal' or the name of the person Dadashri is addressing, the reader should insert his or her name for exact understanding.
1) You need realization of the Self and awareness of the Self in order to go to moksha (ultimate liberation).
2) Moksha (ultimate liberation) cannot be attained until purity arises. To attain purity one has to realize 'Who am I?'
3) When it is called that a mistake is 'seen' (realized) It is when it does not occur again.
Read experience of people after self realization to know how this Gnan (Knowledge of self) works.
