("means of destruction") The Shrividya school of
tantra, a clandestine religious discipline, has a ritual.
The shrichakra, a symbolic diagram used in devotion, is
employed in this ritual.
The adept's ceremonial trip begins on the shrichakra's
periphery, which symbolizes the seemingly "real" daily world, and
progresses to the center, where a single point (bindu) signifies ultimate
oneness.
The ritual process system atically deconstructs the dualistic reality and eliminates the concept of a Self that is apart from the Absolute Reality, which is why it is termed "destruction."
