Yantra Terms

In the Hindu tradition a Mantra is a verbal expression and a Yantra is a visual expression. In the Buddhist tradition a Yantra is called a mandala and three dimensional version is called Kumbum. In the Hindu tradition the Sri Yantra is the source of all yantras and has as its starting point the bindhu (literally a point) and the five activities (Pancha Kriya). The word is usually translated as a machine, but in the special sense of the tantrik tradition refers to the Devi in her linear or geometrical form. Yantras, by the way, are always used flat. They may be two-dimensional or three-dimensional. Every aspect of Devi has her own mantra and yantra. The yantra of Devi Lalita is Shri Yantra. The divinity of the yantra always occupies the centre or apex. http://www.religiousworlds.com/mandalam/tripura.htm Cologne Sanskrit Dictionary: yantra n. any instrument for holding or restraining or fastening , a prop , support , barrier a fetter , band , tie , thong , rein , trace a surgical instrument (esp. a blunt one , such as tweezers , a vice &c. , opp. to {zastra}) any instrument or apparatus , mechanical contrivance , engine , machine , implement , appliance (as a bolt or lock on a door , oars or sails in a boat , &c.) cf. {kUpa-} , {jala-} , {taila-y-} ; ibc. or ifc. often = mechanical , magical) ; restraint , force ({eNa} ind. forcibly , violently) MW. ; an amulet , mystical diagram supposed to possess occult powers
