Whereas Shiva and Parvati try all legitimate ways to take over them.
Medusa and Basilisk - It is advised to avoid eye contact with basilisk the hybrid serpent and snake haired Medusa and hindu mythology's Sani-Saturn. All these folks are evil eyed. If you see all the stories in hindu mythology they have a pattern, all these badguys take non-violence path and fast for days till god shows up. The pleased god or goddess shows up and fulfills their blessings except immortality. The moment they get that, these guys imprison the milksop devas[lessergods] and create chaos in the world. And then the devas run forlife and beg to alpha gods to save them. The trickster Vishnu would always savethe devas by hook or crook.
Same, like kid denying to eat till he gets his xbox :)
Narada-trickster cajoles Ravana to put them on their back to show his virility by walking on their chest instead of their back. The bad guyRavana does that and when Sani's evil eye gazes him,he becomes victim of thebad luck. It starts with kidnapping and rest is history. Yeah.literally , heardabout story of Ramayana?
Moral of the story: Never yield to fasting trick. Let them stay hungry or put them on timeout.
