Well I dont think this book words can be summarised. I ll recommend reading it.
Hope the following may help:
The physical, moral and spiritual states of man
What is the state of man after death?
The object of man's life and the means of its attainment,
The operation of the practical ordinances of the Law in this life and the next
Sources of Divine knowledge.
I read 3 chapters and found nothing wrong but also nothing special. The book is aimed at Hindus and Christians with lots of refs from Quran with simple explanations.
Anyway, I don't have any more questions to ask though I didn't get the satisfactory answers of my questions but that's okay.
Thank you for your replies, Destino and d-tox-ed.
