One ring to rule them all,
one ring to find them,
One ring to bring them all
and in the darkness bind them.

The first part of the name comes from King Ram from the great indian Ramayan and baan the arrow or missile he used to vanquish the great demon / Rakshasa , Ravan. This term was used for a base onion and tomato gravy in my hotel company many many years back which used to go into allmost all the Indian food and thus the second part of the Tolkien title from the One Ring.
