Hanumān_in_the_Rāmāyaṇa_of_Vālmīki
According to one legend, Shiva and Parvati were once playing as monkeys when Parvati became pregnant. Shiva then transferred this pregnancy to Anjana, who had been performing penance to have a child. Thus, Anjana gave birth to Hanuman, who is considered to be an embodiment of Shiva.
