Your own Self-Realisation
is the greatest service you can
render the world.
Your duty is to be, and not to be this or that. "I am that I am" sums up the whole truth...
"I-I" is the Self. "I am this" is the ego. When the "I" is kept up as the "I" only, it is the Self. When it flies off at a tangent and says "I am this or that, I am such and such," - it is the ego.
-The Sage of Arunchala
