Anuttarayoga / Yoganiruttaratantra
Tantras of the highest class, divided into “non-dual,” “mother,” and “father,” and within the two latter categories into six “families” of principal deities.
The Summary of Empowerment is considered to be the only extant portion of the root text of the Kālacakratantra. According to the Buddhist tantric tradition, the Sekkodeśa was transmitted by the Buddha in his emanation as Kālacakra, to Sucandra, the first king of Śambhala. The text’s 174 verses cover a wide range of topics. After a short introduction to the eleven empowerments that constitute a gradual purification of the aggregates, body, speech, mind, and wisdom, the treatise turns to the so-called “sixfold yoga.” It begins by teaching meditation on emptiness via the contemplation of various signs, such as smoke or fireflies. Following the description of the control of winds and drops within the body’s channels and cakras, along with the signs of death and methods of cheating death, the text goes on to describe the three mudrās—karmamudrā, jñānamudrā, and mahāmudrā. After a concise criticism of cause and effect, the text concludes by describing six kinds of supernatural beings closely related to the Kālacakratantra, along with their respective families.
As its title suggests, this tantra is specifically concerned with the proper interpretation, or “resolution,” of the highly esoteric or “secret” imagery and practices associated with deity yoga in both its development and completion stages as described in the Yoginītantra class of tantras.
Equal to the Sky belongs to a series of texts known as the rali tantras, which are primarily associated with the Cakrasaṃvara system but incorporate themes that are also prominent in the Hevajra and Kālacakra systems. The tantra presents a discourse in which the Buddha addresses three types of ḍākinī, explains their true natures, and correlates them with the practitioner’s physical and subtle body.
Written around the tenth or the eleventh century ce, in the late Mantrayāna period, The Tantra of Caṇḍamahāroṣaṇa represents the flowering of the Yoginītantra genre. The tantra offers instructions on how to attain the wisdom state of Buddha Caṇḍamahāroṣaṇa through the practice of the four joys.
