the real Holy_Book of God

There are many religions and many religious books in the world. Are any of these the real holy book of God?
Every religion claims that their religious book is the holy book of God. And all religions also claim that their God is the only real God.
oh my God !
so many religions, so many religious_books, so many it's rules, so many God's.
I had heard in my younger_age from my school teacher that God is only one, the name is different. Destination is same, the way is different. The rules are the same but the way of explaining it is different. The Soul is the same but the body is different according to the climate and gender. feelings are the same, but languages are different to express them.

When I got a chance to meet the spiritual masters, they teach me the reality of God's Holy_Book and it's rules.
they said that God is the super_consious power, the super conscious doesn't write its rules on non conscious things (paper, stone, wood, etc.). The super conscious write its rules on conscious things, and that is your body. The laws of God are written on everyone's body. means your body is the holy_book of God. rules are written in your brain, in your mind, in your heart, in your body's each an every cells.
close your eyes, go inside and read it. keep your body and mind clean from inside, so that you can read it properly.
i asked : how i read it?
they said : it is very simple.
"always be aware from inside, stop reacting, start observing"
formula is very simple, but when doing practically, it is very difficult.
i asked : what i have to do, what to not do?
what is virtue, what is sin?
they said : very simple.
the act done by you, which give happiness to others, that is virtue.
the act done by you, which give sorrow, pain to others, that is sin.
What you give to others, you get it back in return with interest.
pain for pain, sorrow for sorrow, happiness for happiness, respect for respect, cheat for cheat, etc.
choice is yours? what to do, what to not do
i asked : When our body is the Holy Book, then how did many religions and scriptures (religious_books) arise?
they said : When a person tries to read himself, he understands the law of nature and he experiences a lot within himself. When he tells his experiences to others, then his followers write down what he said on paper or something to remember it. Thus his narrated experiences take the form of a book. And as soon as the book is made, a new religion is born.
in short you can say that religious book is the inner experience of someone. And that person is called Messenger of God.
but the real Holy_Book of God is your body. An alive book, conscious book.
if there is any confusion to understand the religious book then try to read the conscious book (your body, mind, heart, brain).
and one thing more: God alway wants to live in conscious, alive temple.

I think that masters gave me the correct information. The Divine Book will be the same for all human beings. Won't be different for everyone.
