Jaya Guru Datta! Sri Guru Datta!
The heat of the radiance became so strong that Fire God was not able to carry it! So he passed it on to Wind God. And now Hanuman will be known to everyone as Vayu putra.
Note that Wind God's vahana is camel - our beloved Hanuman will camel as his vahana as well!
Om Namo Hanumate Namaha!
