Q: Este libro ha sido uno de los mejores libros que he leido, soy adicta a la lectura y este libro me ayudo en muchas formas. Te ensena a analizar muchas cosas, a comprender otras con respecto a la vida y te lleva a tener una mente mas abierta cuando por ejemplo te pone a dudar si hay mas vidas ya que en algunas religiones eso es inconcebible.This book is one of the best books I have ever read, It makes you think and wonder about past life especially if you do not believe in that. I truly recommend this book.
A:
Positive
