Kālá (Sanskrit: काल, IPA: [kɑːˈlə]) (Tamil: காலம்i/ˈ/kaalam or kaala) is a Sanskrit word which means "Time". the tamil meaning of kaalam or kaala also refers "Time". It is also the name of a deity in which sense it is not always distinguishable from kāla meaning "black". It often used as one of the various names or forms of Yama.
Monier-Williams's widely used Sanskrit-English dictionary lists two distinct words with the form kāla.
kāla 1 means "black, of a dark colour, dark-blue ..." and has a feminine form ending in ī – kālī – as mentioned in Pāṇini 4-1, 42.
kāla 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 ā, as mentioned in the ṛgvedaPrātiśākhya. As a traditional Hindu unit of time, one kālá corresponds to 144 seconds.
According to Monier-Williams, kāla 2 is from the verbal root kal "to calculate", while the root of kāla 1 is uncertain, though possibly the same.
As applied to gods and goddesses in works such as the DevīMāhātmya and the SkandaPurāṇa, kāla 1 and kāla 2 are not readily distinguishable. Thus Wendy Doniger, translating a conversation between Śiva and Pārvatī from the SkandaPurāṇa, says Mahākāla may mean " 'the Great Death' ... or 'the Great Black One' ". And SwāmīJagadīśvarānanda, a Hindu translator of the DevīMāhātmya, renders the feminine compound kāla-rātri (where rātri means "night") as "dark night of periodic dissolution".
In Javanese mythology, Batara Kala is the god of destruction. Batara Kala is depicted as giant, born of the sperm of Bathara Guru, the kings of gods.
In Borobudur, the gate to the stairs is adorned with a giant head, making the gate look like the open mouth of the giant. Many other gates in Javanese traditional buildings have this kind of ornament. Perhaps the most detailed Kala Face in Java is on the south side of Candi Kalasan.
