"The eleventh-century Seventeen Tantras are among the most important texts in the tradition of the Great Perfection-and in all of Tibetan Buddhism. This set provides these two luminous root texts in crystal-clear translation, along with their commentaries, which break down the tantra passage by passage under headings that contextualize many instructions for the practice of the Great Perfection. The two texts are published together because they contain some of the most detailed expositions on which are based the two essential practices of the Great Perfection: trekchö (cutting through delusion to innate empty essence, the primordial purity of the nature of mind) and thögal (skillful means, the spontaneous presence of primordial purity of mind; effortless and immediate crossing the illusory gap between perceiver and perceived, effortless shift from dualistic perspective directly to the nonduality that is innate rigpa). The Tantra Without Syllables focuses on the theoretical basis for trekchö, and the Blazing Lamp focuses on the theoretical basis of thögal. The actual tantra discussed is not the body of the root text of the tantra, but rather the subject matter that the root text points to: the continuum of one's own vidyā confirmed in a direct perception, which cannot be explained in words. (Tantra of the Blazing Lamps discusses how a luminous awareness, located at the heart, can be projected through the eyes and seen in vision.) Malcolm Smith's simple and lucid introductions bring clarity to an intricate subject, making these volumes vital reading for any student of Dzogchen"--
