The English translation of this book can be improved, as the Chinese version is much better.
I first read this book and could not comprehend its contents until I read "Encounters with the Spiritual World" also written by Master Sheng-Yen Lu. In order to understand the meaning behind this book it is important to have read Grand Masters other books about his experiences. After going back to "A detailed exposition on the true buddha tantric dharma" I was actually able to follow the instructions to better my meditation. I also recommend going to a local True Buddha chapter for help in the practices. Having read this book I have experienced many phenomenons in practicing the guru heart practice and recommend it to everyone to try. I am sure if they pray wholeheartedly they too will experience spiritual healing.
