Your own Self-realization is the greatest service you can render the world.

The question 'Who am I?' is not really meant to get an answer, the question 'Who am I?' is meant to dissolve the questioner.

Apart from the body does the world exist? Has anyone seen the world without the body?

The world is illusory, Only Brahman is real, Brahman is the world

From where does this "I" arise? Seek for it within; it then vanishes. This is the pursuit of wisdom. When the mind unceasingly investigates its own nature, it transpires that there is no such thing as mind. This is the direct path for all. The mind is merely thoughts. Of all thoughts the thought "I" is the root.

Wanting to reform the world without discovering one's true self is like trying to cover the world with leather to avoid the pain of walking on stones and thorns. It is much simpler to wear shoes.
