Dzogchen, the Great Perfection, a.k.a. Atiyoga, has, since its inception, been proclaimed by Tibetan gurus to be the pinnacle of all spiritual paths, the most direct way for a yogi to achieve Buddhahood. Therefore, given L. Ron Gardner's affinity for the highest yoga teachings, it's no surprise that he became smitten with the tradition after he encountered it in the late 1970s through the writings of the esteemed Namkhai Norbu.

In the decades that followed, L. Ron read numerous Dzogchen texts by both modern and early Tibetan masters. As a burgeoning expert in mystical traditions who specialized in comparative spirituality, he wanted to understand and be able to explain Dzogchen in relation to other great spiritual traditions. And when, some fifteen years ago, he "cracked the code" of the En-Light-enment project, he knew it was just a matter of time until he applied his seminal insights to explicating the Great Perfection.

Regarding Radical Dzogchen, L. Ron writes: "My goal as a mystic-philosopher has always been, and will always be, the radical demystification of spiritual life. And I trust that those who resonate with my goal will appreciate the unique and ground-breaking material in this book."
