Two of the best books I have ever read are
The World's Religions written by Huston Smith many years ago
written by Reza Aslan very recently.
Both are available as Ebooks on Amazon.
I highly recommend both!
However, for those of you are too busy to read the whole books,
there is an alternative.
I went through both books very carefully and picked out the highlights
]Honestly, who else love you that much?]
