About Guhyasamāja Tantra

The Guhyasamāja Tantra is one of the most important scriptures of Tantric Buddhism. In its fullest form, it consists of seventeen chapters, though a separate "explanatory tantra" (vyākhyātantra) known as the Later Tantra is sometimes considered to be its eighteenth chapter. Many scholars believe that the original core of the work consisted of the first twelve chapters, with chapters thirteen to seventeen being added later as explanatory material.
