[Lord Shiva said to Lord Kalki:] "This horse was manifested from Garuda, and it can go anywhere at will and assume many different forms.
Here also is a parrot [ Shuka ] that knows everything - past, present, and future.
He is, for example, only an invisible force destroying evil and chaos in some texts, while an actual person who kills those who persecute others, and portrayed as someone leading an army of Brahmin warriors in some.
His mythology has been compared to the concepts of Messiah, Apocalypse, Frashokereti and Maitreya in other religions. In Tibetan Buddhism, the Kalachakra-Tantra describes 25 rulers, each named Kalki who rule from the heavenly Shambhala.
Kalki, also called Kalkin, is the tenth avatar of Hindu god Vishnu to end the Kali Yuga, one of the four periods in endless cycle of existence (krita) in Vaishnavism cosmology.
I would also like to present You this sharp, strong sword and so please accept it.
The handle of this sword is bedecked with jewels, and it is extremely powerful.
According to Dimmitt, this was likely because just like the concept of the Buddha as a Vishnu avatar, the concept of Kalki was "somewhat in flux" when the major Puranas were being compiled.
This myth may have developed in the Hindu texts both as a reaction to the invasions of the Indian subcontinent by various armies over the centuries from its northwest, and the mythologies these invaders brought with them.
He is described in the Puranas as the avatar who rejuvenates existence by ending the darkest and destructive period to remove adharma and ushering in the Satya Yuga, while riding a white horse with a fiery sword.
