Kalachakra is one of the most well-known meditational deities of Anuttarayogatantra.
It is associated with the salvific myth of Shambhala and this deity is highly venerated amongst the laity.
Most Tibetans try to receive the empowerment of Kalacakra at least once during their
life since there is a popular folk belief that attending this empowerment will ensure a birth in the mythical land of
Shambhala in the future. However, on a more serious level this tantra is one of the richest sources for the
study of the Buddhist systems of cosmology, astrology, astronomy, subtle energy systems, mind/body relationships
and various other related topics. The Kalacakra tantra and its commentaries also include profound explanations of the
practice of Kalacakra and its theoretical foundations.
