Equal to the Sky

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. A primary concern of this text is to explain advanced yogic practices performed during the completion stage (Skt. utpanna­krama/­niṣpanna­krama; Tib. rdzogs rim) in the Yoginī Tantras, but it also treats a wide range of topics including astrology, sacred geography, and tantric hermeneutics. The result is a text which, while very dense and quite difficult to engage with, rewards the reader by bringing together an astonishingly vast range of topics concerning both the theory and practice of Buddhist tantra.
