Kala (), ) is a Sanskrit term that means "time" or "death." As time personified, destroying all things, Kala is a god of death, and often used as one of the epithets of Yama. In Shaivism, Kala is known as the fiery avatar of Shiva Kala Bhairava or Kalagni Rudra; and in Vaishnavism Kala is also associated with Narasimha and Pralaya. As applied to gods and goddesses, is not always distinguishable from , meaning "black." Etymology Monier-Williams's widely used Sanskrit-English dictionary lists two distinct words with the form : 1 means "black, of a dark colour, dark-blue ..." and has a feminine form ending in – – as mentioned in 4–1, 42. 2 means "a fixed or right point of time, a space of time, time ... destiny, fate ... death" and has a feminine form (found at the end of compounds) ending in , as mentioned in the . As a traditional Hindu unit of time, one kālá corresponds to 144 seconds.

At the end of the story, Time, in the form of inevitability or necessity, informs Rama that his reign on Earth is now over.
