One among the numerous names of Hindu God Ayyappa is Kaliyuga Varada. The popular belief is that Ayyappa protects the devotees in Kali Yuga until the arrival of the Kalki Avatar of Sri Vishnu. This is the reason why Ayyappa is also known as Kaliyuga Varadan.
Like Kalki, the vehicle, or Vahana, of Ayyappa is a horse. Kalki, the tenth incarnation of Sri Vishnu, will put an end to the present cycle of creation and usher in the changes on earth required for the next cycle of creation.
In Kali Yuga, Ayyappa protects those devotees who follow the path of Dharma. He is Kaliyuga Varadan. He annihilates Adharma and makes sure that those devotees who observe Dharma attain Moksha.
