I am Asian and in Asian mythology like epics like Mahabharatha, when some person is going to do something bad then a voice from nowhere comes from background, after a thunder or something, to stop him or to warn him.
A specific case would be (Some one who knows Mahabharatha could relate to it): When Bhisma uses a Powerful arrow against the rival in a competition, a voice comes after a thunder warning him the supernatural arrows should not used for fun and selfish reasons Video clip. Like this, God's voice comes multiple times in this epic. I would like to know the word for it in English.
In Tamil my regional language, it is called "Asariri". But this word is also used in situations where you tell something and the bell rings then it is a confirmation from god or nature accepting the statement.
