juggernaut: [17] Hindi Jagganath is a title of Krishna, one of the avatars, or incarnations, of the god Vishnu, the Preserver. It comes from Sanskrit Jagganātha, a compound of jagat- ‘world’ and nāthás ‘lord’. It is applied also to a large wagon on which an image of the god is carried in procession (notably in an annual festival in Puri, a town in the northeastern Indian state of Orissa).

It used to be said, apocryphally, that worshippers of Krishna threw themselves under the wheels of the wagon in an access of religious ecstasy, and so juggernaut came to be used metaphorically in English for an ‘irresistible crushing force’: ‘A neighbouring people were crushed beneath the worse than Jaggernaut car of wild and fierce democracy’, J W Warter, Last of the Old Squires 1854.

The current application to large heavy lorries is prefigured as long ago as 1841 in William Thackeray’s Second Funeral of Napoleon (‘Fancy, then, the body landed at day-break and transferred to the car; and fancy the car, a huge Juggernaut of a machine’); but it did not become firmly established until the late 1960s.

juggernaut (n.)youdaoicibaDictYouDict
1630s, "huge wagon bearing an image of the god Krishna," especially that at the town of Puri, drawn annually in procession in which (apocryphally) devotees allowed themselves to be crushed under its wheels in sacrifice. Altered from Jaggernaut, a title of Krishna (an incarnation of Vishnu), from Hindi Jagannath, literally "lord of the world," from Sanskrit jagat "world" (literally "moving," present participle of *jagati "he goes," from PIE *gwa- "to go, come" (see come (v.)) + natha-s "lord, master," from nathate "he helps, protects," from PIE *na- "to help." The first European description of the festival is by Friar Odoric (c. 1321). Figurative sense of "anything that demands blind devotion or merciless sacrifice" is from 1854.
