The Secrets of God is a book of his research and a collection of notes. He started this research in an early age borrowing books from British and American Libraries in Mumbai. Much of his work is based on divine scriptures. Quoting verses from Old Testament, Bible, Quran and Vedas, with striking resemblance he is revealing the unknown Secrets of God. The resemblance of verses from divine religions has been discussed by many scholars. Here, in this book Sid tries at ‘reasoning’. And this reasoning develops striking secrets of God. There are new subjects related to the Supreme God which are not discussed by scholars so far. AQ Sid is treading on this unknown Terrans. A chapter in this book, “Why Messengers were sent to mankind and what were the reasons behind the miracles of Messengers” has a very strong reasoning. The facts and reasons behind miracles of Messngers are truly revealing a ‘secret of God’. Another chapter, ‘Age, Fate and destiny’ is also linking these most talked about subjects to a secret of God. There are no exhaustive lecturing or discussions in any chapter. All chapters are concise and well supported by valid reasoning in an interesting narration. The book also justifies why there are different faiths while the Creator is only One. This chapter will give enough food for thought for any inter faith event.
