In this book I offer you translations of eight seminal Tantras that are preserved in the Nyingma Gyubum. The first book herein, The Great Tantra that is Unwritten, is one of a set of seventeen famous Tantras known as the Upadesha Instruction Section (Man ngag sde). In addition, readers who are interested in feminine presentations of enlightenment will find many books of interest within this volume. The Vajra Yogini Tantra, the Tantra on the Undisturbed Arali, and the Tantra of the Goddess Light Rays (Marici) are specifically devoted to the concerns of dakinis and goddesses, while the Tantra on the One-Pointed Samadhi of Avalokiteshvara represents the questions of the dakini Sun Garland and the Tantra on the Self-Liberation of Samsara for the Unmoving One represents the questions of the dakini Lightening Garland. The Tantra on the Flawless Jewel and the Tantra on the Bodhicitta: Grabbing the Peacock by the Neck both represent profound and insightful instructions on the experience of enlightened awareness. I have included images of the Tibetan manuscript for your convenience and to help preserve this important literature.
