In mythology, we often come across stories where gods swallow and regurgitate various beings. Greek god Cronus swallows his own children until he is forced to vomit them out. The regurgitated gods attack Cronus and defeat him in battle.

In Hindu mythology, during the battle between the devas and asuras, the guru of the asuras, Shurkracharya, is about to use Sanjeevani Vidya to resurrect all dead asuras. To prevent this from happening, the gods beg Shiva to help. Shiva swallows Shukracharya and keeps him in his body. But Shurkracharya manages to escape in the form of semen. This is why “shukra” means semen.
