Kesari was a male
vanara who was brave and inquisitive by nature–and a chief. He was the father of the Hindu god
Hanuman and husband of
Anjana. Before Hanuman was born, Kesari used to wander around to different holy places, and whenever he found a scenic garden, he would sit in long meditation. Together with Anjana, he prayed to the god
Shiva for a son. Shiva, pleased by their devotion and prayers granted the request and Shiva was born to Anjana, later named Hanuman. This is why Hanuman is also called Rudra, another name Shiva was known by.
