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 summed up in the words 'Be still'.
What does stillness mean? It means destroy yourself. Because any form or shape is the cause for trouble. Give up the notion that 'I am so and so'.
All that is required to realize the Self is to be still. What can be easier than that?
Your own Self-Realization is the greatest service you can render the world.
~ Ramana Maharshi
