A well written book that helps to reinforce one's faith and give new meanings to the definition of GOD. The book provides simple, scientific explanations to some of the spiritual concepts to connect them to the natural phenomena.
The chapters like "Tree of Life" gives good analogues that help a common reader understand the complex concepts in life. A few chapters were tough, but again it helps to challenge the reader's mind.
I should admit though that, at times, "Aliyah" is being very modest in saying "...it is not difficult to understand..." that she considers "Emma and Theo" to be at par with her own intellect...
