To live without self-concern.
Abandon all self-concern, worry not about your welfare, material or spiritual, abandon every desire, gross or subtle, stop thinking of achievement of any kind. You are complete here and now, you need absolutely nothing.
For this you must know your own true being as indomitable, fearless, and ever victorious. Once you know with absolute certainty that nothing can trouble you but your own imagination, you come to disregard your desires and fears, concepts and ideas and live by truth alone.
I AM THAT - Nisargadatta Maharaj
