I found an excellent and comprehensive article on Sri Nisargadatta Maharaj available here: http://www.enlightened-spirituality.org/Nisargadatta_Maharaj.html
The multidimensional article is written by Timothy Conway who is the author the well received book 'Women of Power and Grace: Nine Astonishing, Inspiring Luminaries of Our Time'.
"My Guru told me: “...Go back to that state of
pure being, where the ‘I am’ is still in its purity before it got
contaminated with ‘I am this’ or ‘I am that.’ Your burden is of false
self-identifications—abandon them all.” My guru told me, “Trust me, I
tell you: you are Divine. Take it as the absolute truth. Your joy is
divine, your suffering is divine too. All comes from God. Remember it
always. You are God, your will alone is done.” I did believe him and
soon realized how wonderfully true and accurate were his words. I did
not condition my mind by thinking, “I am God, I am wonderful, I am
beyond.” I simply followed his instruction, which was to focus the mind
on pure being, “I am,” and stay in it. I used to sit for hours together,
with nothing but the “I am” in my mind and soon the peace and joy and
deep all-embracing love became my normal state. In it all
disappeared—myself, my guru, the life I lived, the world around me. Only
peace remained, and unfathomable silence. (I Am That, Dialogue 51, April 16, 1971)"
"The Maharaj always taught that one must stand
prior to all identifications with "I am this" or "I am that" and dwell
in the basic "I am" sense until the Divine Grace of one's Real Nature
awakens one to the Absolute Awareness beyond even the "I am"-sense."
