The entire meaning of the subject matter of the Kalachakra tantra is included within the three Kalachakras, or Wheels of Time: The Outer Wheel of Time, the Inner Wheel of Time, and the Other Wheel of Time. The Outer Wheel of Time is the external world of the environment, and it is also called “The procession of the external solar and lunar days.” The Inner Wheel of Time is the human body, that is an inner Jambudvipa, or earth-surface. Likewise, the inner channels, elements, and movements of the winds are set forth as the Inner Wheels of Time. The Other Wheel of Time is the initiations and paths of Shri Kalachakra, together with their results. It is “other” than the preceding two Wheels of Time. The guru ripens the disciple’s psycho-physical continuum with the initiations, and the disciple meditates on the path that consists of the generation process and the completion process. In this way the yogi actualizes the resultthe buddha body that is the divine image of emptiness. This is the Other Wheel of Time.
