In Hinduism, Kala is also known as the god of death. Kala is a manifestation of Yama, lord of the underworld and destruction. In Vedic mythology, Yama was thought to be the first mortal to die and was, therefore, made to guide all others who came after him into the underworld.
In Buddhism, especially Tibetan Buddhism, Kala is time personified. He appears as a deity in the form of Mahakala. Mahakala means "great death" in Sanskrit and is frequently depicted as a wrathful protector deity on temple walls and in religious paintings. In Hinduism, Mahakala can also be another name for the god, Shiva.
