Avadhuta

(“one who has cast away [all attachments]”) In its most general sense,
an avadhuta is an ascetic who does
not adhere to any social or religious
rules but his (or far more rarely,
her) own. Needless to say, their
behavior is often unpredictable, seemingly capricious, and sometimes
intentionally shocking.
As a more technical title, avadhuta
is a term of respect for the senior
members of the Naga class of the
Dashanami Sanyasis, renunciant
ascetics who are devotees (bhakta)
of the god Shiva and who formerly
made their living as traders and
mercenary soldiers.
