This books shows that prophecies in Buddhist scriptures about the coming of another Buddha, called Maitreya, were fulfilled in the person of the Prophet Muhammad
I think this kind of amalgam of back and forth philosophical analysis is dependant on emotions heavly. I mean I am of islamic faith but can see that the coming Buddha is christ in his second coming which as Muslims believe in second christ coming. I mean it seems that Buddhism could have been a monotheistic faith that got distorted which is the strongest most well studied point in the book but to say with confidence they predicted Jesus or Muhammad peace be upon them is a bit of a stretch I think. However I respect the effort.
