Kālacakra ( dus kyi ‘khor lo) is a polysemic term in Vajrayana Buddhism that means “wheel of time” or “time cycles”.[1] “Kālacakra” is also the name of a series of Buddhist texts and a major practice lineage in Indian Buddhism and Tibetan Buddhism. The root text of the Kalachakra Tantra was first revealed by the Buddha Shakyamuni as the magical manifestation of the Kalachakra deity to King Suchandra of Shambhala who traveled to India in order to request and receive this tantra. At the glorious Drepung stupa in South India, a year after his complete enlightenment, it is said that the Buddha displayed the Wondrous Lunar Mansion Mandala, performed the Kalachakra empowerment and taught the tantra to King Suchandra and countless other human and non-human beings. Upon returning to the realm of Shambhala, King Suchandra began teaching and transmitting the Kalachakra Root Tantra. This tantra has then been passed down successively to the present 21st Kalkin of Shambhala. King Yashas, an emanation of Manjushri then composed the Condensed Kalachakra Tantra while his son, Kalkin Pundarika composed the primary commentary on the Condensed Kalachakra Tantra titled, Vimalaprabha or Stainless Light.

Along his way, Jamyang Dorje encountered an emanation of the 11th Kalkin of Shambhala who performed the entire Kalachakra empowerment and transferred this tantric lineage of realization onto him. After meditating for 6 months on the profound yogic practices that he received from the Kalkin, Jamyang Dorje was able to transport himself to Shambhala. While there in Shambhala, he studied the Kalachakra Tantra further with the Kalkin before returning to India. Upon his return, Jamyang Dorje became known as “Kalachakrapada the Elder.” The way these teachings  spread into Tibet.  Kache Banchen Dawa Gonpo, a direct student of Nalanpa came to Tibet three times. He gave the entire empowerment of Kalachakra, and translated by Dro She Rab Dra, he gave the teachings of Kalachakra Tantra and many other teachings such as the trilogy of Commentaries by Bodhisattvas. Then they were promoted gradually by
