The book provides the truth of Buddhism history and the basic Buddhism principles, such as the Four Noble Truth and the Noble Eightfold Path, which have been misunderstood for thousands of years due to the misleading transmission of the nonenlightened monks and now have been thoroughly recognized and explained by the enlightened master Thích Thanh Thin with the knowledge inherited from his master, Thích Thông Lc. As an enlightened one, he shares his own practicing methods that focus on capturing and controlling the operation of Consciousness and Subconsciousness, the two factors that have contributed to all the misunderstandings in history and principles and interrupts the path to enlightenment ever since. His methods are very simple yet unique and effective and to be demonstrated by his explanation and evidence in the book.
