According to the Kālacakra tantra, Suchandra, dharmaraja of Shambhala, requested that Gautama Buddha teach him how to practice the dharma without renouncing worldly responsibilities.
The Kālacakra deity represents a buddhahood and thus omniscience.
Since Kālacakra is time and everything is the flow of time, Kālacakra knows all.
Mañjushrīkīrti (Tibetan: , THL Jampel Drakpa) is said to have been born in 159 BCE and ruled over Shambhala, which had 300,510 followers of the Mleccha religion living in it, some of whom worshiped the sun.
He is said to have expelled all the heretics from his dominions but later, after hearing their petitions, allowed them to return.
The phrase "as it is outside, so it is within the body" is often found in the Kālacakra tantra to emphasize the similarities and correspondence between human beings and the cosmos; this concept is the basis for Kālacakra astrology, but also for more profound connections and interdependence as taught in the Kālacakra literature.
In Tibet, the Kālacakra astrological system is one of the main building blocks in the composition of Tibetan astrological calendars.It is an active Vajrayana tradition, one offered to large public audiences.The tradition combines myth and history, whereby actual historical events become an allegory for the spiritual drama within a person, drawing symbolic lessons for inner transformation towards Buddha nature.Kālacakri, his spiritual consort and complement, is aware of everything that is timeless, not time-bound or out of the realm of time.In Yab-Yum, they are temporality and atemporality conjoined. The term "wheel" evoked herewith is a principal polyvalent sign, teaching tool, organising metaphor and iconographic device within Indian religions.Some Buddhist masters assert that Kālacakra is the most advanced form of Vajrayana practice; it certainly is one of the most complex systems within tantric Buddhism.
