The symbolism of the Kalacharka's stacked syllables is extremely complex, encapsulating meanings which relate to all three aspects of the Kalacharka Tantra - the external, internal, and alternative. The external deals with cosmology, astronomy, and astrology; the internal aspects deals with the subtle energy systems of the individual's mind and body interrelationships; and the alternative aspect deals with the actual deity practice of Kalacharka.

The Kalachakra Mandala is also represented with one of the most important and well known symbol of the Tibetan Tantric tradition: the Sanskrit seed syllables of the Kalachakra system known as “the mighty ten stacked syllables”. Each syllable that compose the mantra has a different color and they are represented all interconnected on top of a lotus flower and surrounded by a ring of fire.
