The K¿lacakra Tantra was the last major T¿ntric text composed before the decline of Buddhism in India. Over the course of its thousand-year journey, the book has left an indelible influence over different regions of Asia. Apart from the Vimalaprabh¿ commentary composed during the mid-eleventh century, no verse-by-verse commentary is available to the general reader. Kumar has translated the entire 1,047 stanzas of the text written in Sragdhar¿ metre. In addition, he has produced distinct volumes of fresh, in-depth commentary for each of the five chapters of the original Sanskrit text. The first volume was published in 2022. This second volume delves into the understanding of the inner K¿lacakra. The internal mechanisms of winds, subtle veins and cakras have been explored with clarity. In Indic tradition, häha-yoga has been propounded for the first time in this section of the K¿lacakra Tantra.
