In Tibetan Buddhist tradition, Shambhala, also spelled Shambala or Shamballa, is a spiritual kingdom. Shambhala is mentioned in the Kalachakra Tantra. The Bon scriptures speak of a closely related land called Tagzig Olmo Lung Ring.

Kālacakra is a polysemic term in Vajrayana Buddhism as well as Hinduism that means "wheel of time" or "time cycles". "Kālacakra" is also the name of a series of Buddhist texts and a major practice lineage in Indian Buddhism and Tibetan Buddhism. The tantra is considered to belong to the unexcelled yoga (anuttara-yoga) class.
