Abstract
The Kālacakra tradition positions itself in the philosophical system of Madhyamaka, from whose perspective it criticizes the doctrinal tenets of Hindu philosophical schools and of Buddhist schools other than Madhyamaka. The concept of emptiness is the most essential tenet of the Kālacakratantra practice. Before analyzing the practical applications of the doctrine of emptiness in the Kālacakra tantric tradition, it may be useful to examine first the ways in which emptiness is defined and explained in this tantric system. Diverse manners of explaining emptiness result from the various contexts in which this tradition applies and actualizes the doctrine of emptiness. In conclusion, one can say that the sole purpose of the intricate system of the Kālacakratantra's yogic practices is to awaken the yogi to the gnosis of emptiness. The tantra's expositions on emptiness are adopted from the Perfection of Wisdom literature and from Madyamaka.
