Kali
(Sanskrit कलि or काली, “the black one, night, goddess of time”) In the sacred Vedas, this name refers to one of the seven tongues of Agni, the god of fire. The meaning has since changed to refer to the goddess Kali, the consort of Shiva.
The name Kali is derived from ka, the first consonant of Sanskrit, and which can mean “time, pleasure, light, sound, sun, air, soul, wealth, water, head, fire, body,” and much more. Further, kā means “seek, desire, yearn, love.” The second syllable lī means “to melt, liquefy, dissolve.” Thus, in Tantra, the goddess Kali represents the power that can dissolve desire. Desire is the glue that binds us to suffering. Conversely, in negative forms of Tantra, Kali is worshipped as a fulfiller of desire, that which binds us to lust.
Kali Yuga
Literally, “the black era.” Sanskrit काली kali, “black, night, discord, strife” and युग yuga, “age, era, period of time.” Tibetan: snigs-ma’i dus, literally “the degenerate age.”
