It is said that a good brotherly feeling with a sense of equality is the supreme goal to be reached collectively by all members of the community. - Ramana Maharshi

Your duty is to be, and not to be this or that. I Am That I Am sums up the whole truth; the method is summarized in Be Still.

Non-action is unceasing activity. The sage is characterized by eternal and intense activity. His stillness is like the apparent stillness of a fast rotating gyroscope.

The Self is only one. Do you feel hurt if you blame yourself or scorn yourself for your errors? If you hold the Self there is no second person to scorn you. When you see the world you have lost hold of the Self. On the contrary, hold the Self and the world will not appear.
