One of the most
recognizable things in Hindu imagery is a club or staff topped with a human
skull.
At times the shaft of the staff was constructed from another
human bone, such as a thigh or an arm bone.
The deity Shiva is most closely identified with this emblem.
Its usage depicts his outcast, uncontrollable personality,
as well as his complete alienation from mainstream society's normal ideals.
Ascetics, for whom Shiva is the model ascetic and a model for
emulation, nonetheless carry it on occasion.
