Anjana, a beautiful Apsara in celestial palace court of Lord Brahma was cursed by a sage that, the moment she fell in love her face would transform to that of a monkey. Lord Brahma thought of helping her and she took birth on Earth. Later, Anjana fell in love with Kesari, the monkey king and they both married each other. Being an ardent devotee of Lord Shiva, she continued with her tapasya to please the God. Lord Shiva was impressed and she wished him to be her son so that she would be freed from the curse of the sage.
Few days later, King Dasrath was performing a yagna after which the sage gave him kheer to feed all his wives. A portion of Kaushlya, his eldest wife, was snatched by a kite who flew all the way where Anjana was meditating. Lord Vayu (aka Pawan – Wind) on the signal of Lord Shiva kept the khee r in Anjana’s hand. Thinking it as Lord Shiva’s prasad Anjana ate it and thus gave birth to his incarnation – Pawan Putra Hanuman , the son of the Lord of the Winds.
