In my previous book, The Real Spiritual Enlightenment, I briefly introduced what the real spiritual enlightenment truly means, the importance of the true master, and the common questions about spiritual enlightenment. In The Real Spiritual Enlightenment 2, I begin with widely practiced methods of spiritual enlightenment and present approaches suitable for the early stage through the middle and later stages of spiritual enlightenment. These methods are largely those I have personally practiced or commonly observed, allowing readers to gain clarity. I will also highlight what these methods are intended to accomplish, along with the potential difficulties and limitations they may involve. I will recommend certain methods for spiritual seekers who have the opportunity to reach the middle and later stages of spiritual enlightenment. This book will also explain the relationship between the true Self and methods of spiritual enlightenment, so that spiritual seekers may have the opportunity to attain the awakening of the true Self. Finally, as mentioned in The Real Spiritual Enlightenment, this book will briefly introduce the spiritual knowledge of our lineage, so that spiritual seekers may have the opportunity to enter into the middle and later stages of spiritual enlightenment. Relying solely on methods of spiritual enlightenment, even if one exhausts an entire lifetime, makes it difficult to truly enter these deeper stages. This is because the correctness of one’s spiritual understanding determines whether a person can truly integrate into the real spiritual enlightenment and continue progressing into the middle and later stages. In conclusion, this book will also attempt, from my own perspective, to explain the definition of “God,” offering a concise discussion on whether God exists and what God may be.
