Since she could take any form at her wish, once she was roaming around wearing yellow silken clothes with red border on a mountain. Vaayu Dev saw her and lifted her clothes. He found her beautiful, so he hugged her dearly. Anjanee felt the hug, so she said - "Who is that who is trying to break my vow of Paativrat (one man one wife)?"

Hearing this Vaayu Dev said - "I am not breaking your Paativrat so you need not to fear me. I am the all-permeable Vaayu Dev. My hug will give you a brave and mighty son. That son will be like me in jumping and swimming etc." Anjanee got very happy to hear this from Vaayu Dev. Then Hanumaan was born in a cave.

When Dasharath, the king of Ayodhyaa, was doing Yagya to get a son; and Agni Dev gave him a pot of Charu (divine Kheer), a bird took out some Charu from it and while flying over a forest dropped it. Pavan Dev helped putting it in outstretched hands of Anjanee, and Anjanee ate it soon. Then she gave birth to Hanumaan. Thus Hanumaan was the incarnation of Shiv, in a monkey's physical form through the grace and blessings of Pavan Dev. Anjanee and Kesaree were his earthly parents.
