Sanskrit: Kalachakra Tibetan: Du kyi kor lo
Kalachakra is surrounded by eight couples in embrace. Outside of that are six concentric weapon wheels: jnana, bhumi, vari, jvala, vayu and akasha. Each of the wheels has eight couples in embrace. The mandala palace is circular with eight gates. Surrounding the palace is the ring of sixteen great charnal grounds unique to the Kalachakra Tantra. There are usually eight charnal grounds surrounding the mandala palace of a semi-wrathful or wrathful deity.
