Jai Sai Master, Babu garu..
Jai Sai Master, Sai Bandhus..
I have "HEARD" the book!! When I was in Canada, a couple invited me when they came to know that I pray to Sri Sai Baba. They said, they are doing Guru Charitra samoohika parayana (ekaaham). I was very happy and went there.
When I reached the place what I found out was, they were doing the parayana of this book. I am not in a position to give my feedback exclusively but all I can say is, it describes the statistics, history, and miracles performed by Sri Padavallabha Swamy. I had to sit through the parayana and I was there till the entire book was read out.
No other book mentions the efficacy of Sadguru Tatwam as effectively as Sri Guru Charitra, specifically written by Master garu (I know, some of you might be thinking "there he goes again, talking about Master...I can't help it

"!!!). Just as Sai bandhu Asterias garu mentioned, my intention is not at all to belittle that book. I am sharing what I know and what I went through.
Just imagine, almost every chapter has an introduction which gives the significance of Sri Guru. How wonderful it is to know the signifiance of Twashta who secures everything that His Guru asks for. But how well do we know the deeper aspect of it?? It is only mentioned in Sri Guru Charitra of the deeper signifiance. Otherwise we will think "wow! He is a great disciple, he got everything that his guru asked for". But how did he get it?? what is the significance?? And it even mentions further down in the following chapters, that Sri Guru asks all of us to obtain such a status as "padukas" (you know what?? I feel so stupid to put it in English, I hate it....

)
All these explanations are not given in other books which covers history of Sadgurus. I believe that if we give enough concentration and dedication on the introduction of each of those chapters, we will understand those chapters and in turn the essence of Mahatmas, in a lot lot better way.
Best Regards,
Jai Sai Master!
