The above file is a very precious translation of Abdul Baba's book where he would write down the words of Sai Baba. Later on in life he would use this to make predictions and they all came true. Another file is a brief Bio on Abdul Baba and how the notebook came into existence.
Below is a photograph of the original manuscript which is shared in the book Ambrosia in Shirdi by Dr Vinny Chitluri. She had access to the manuscript about 30 years ago where she was allowed to photograph it.
