No, present moment cannot be the same as Brahman realization. One realizes Brahman after chittasuddhi (purity of heart). Chittasuddhi cannot be obtained by simply reading a book.
MASTER (to the Brahmos): "Dive deep. Learn to love God. Plunge into
divine love. You see, I have heard how you pray. Why do you Brahmos
dwell so much on the glories of God? Is there such great need of your
saying over and over again, 'O God, You have created the sky, the

"Everybody is wonder-struck at the mere sight of a rich man's garden
house. People become speechless at the sight of the trees, the
flowers, the ponds, the drawing-room, the pictures. But alas, how few
are they who seek the owner of all these! Only one or two inquire
after him. He who seeks God with a longing heart can see Him, talk to
Him as I am talking to you. Believe my words when I say that God can
be seen. But ah! To whom am I saying these words? Who will believe me?
"Can one find God in the sacred books? By reading the scriptures one
may feel at the most that God exists. But God does not reveal Himself
to a man unless he himself dives deep. Only after such a plunge, after
the revelation of God through His grace, is one's doubt destroyed. You
may read scriptures by the thousands and recite thousands of texts;
but unless you plunge into God with yearning of heart, you will not
comprehend Him. By mere scholarship you may fool man, but not God.
"Scriptures and books — what can one achieve with these alone? Nothing
can be realized without His grace. Strive with a longing heart for His
grace. Through His grace you will see Him and He will talk to you."
