The Laghutantraṭīkā by Vajrapāṇi

«The Laghutantraṭīkā by Bodhisattva Vajrapāṇi is a work that belongs to the tantric phase of Indian Buddhism. Its main peculiarity is that it adheres to the doctrines of two tantric cycles, the Cakrasaṃvara and the Kālacakra. Indeed, it is a commentary on the first chapter of the ātantra, the basic text of the homonymic tradition that is little known in the West: the present work is the first edition of a commentary on the ātantra. At the same time, however, the Laghutantraṭīkā is also one of the most important texts of the Kālacakra, the last tantric school that developed in India. The Sekoddeśa, the Vimalaprabhā, the Hevajratantrapiṇārthaṭīkā and Vajrapāṇi's work are the first texts of this tantric tradition.[…]»
