Vajrasekhara Sutra
Overview
The Vajraśekhara Sūtra is an important Buddhist tantra used in the Vajrayāna schools of Buddhism, but can refer to a number of different works. In particular a cycle of 18 texts studied by Amoghavajra (a Patriarch of Chinese Esoteric Buddhism), which included both Tattvasaṃgraha Tantra, and the Guhyasamaja Tantra, a Tibetan text which appears to be composed of two works grouped together and to further confuse matters in the Japanese Shingon school the Sarvatathāgatatattvasaṃgraha Tantra is known by this name. In Tibetan it is considered to be the main representative of the Yogatantra class of texts.
