As per the Ananda Ramayana, Hanuman is Rama’s brother and is
born of the same sacred sweet that made Dasaratha’s wives pregnant. Dasaratha,
the king of Ayodhya, performed Putrakameshti Yagna in order to have children.
The king received a sweet pudding from the Yaga and it was shared by the king
among his three wives.
Vayu, the wind god, in the form of hawk, pecked a bit of the
pudding from the hands of Sumitra, the youngest wife of Dasaratha.
Anjana was worshipping Shiva for many years in order to get
a powerful child. Shiva was pleased with her tapasya and had told her to raise
her palms to the sky and wait patiently.
The hawk dropped the sweet pudding in the hands of Anjana.
She consumed the sweet pudding and Hanuman was born to her
as a result of this. Thus Hanuman is the half brother of Sri Ram according to
Ananda Ramayana.
