Sri Slothrop

[s~Z]

He's kept alone. If others have seen him or his fire, they haven't tried to
approach. He's letting hair and beard grow, wearing a dungaree shirt and
trousers Bodine liberated for him from the laundry of the John E. Badass.
But he likes to spend whole days naked, ants crawling up his legs,
butterflies lighting on his shoulders, watching the life on the mountain,
getting to know shrikes and capercaillie, badgers and marmots. Any number of
directions he ought to be moving in, but he'd rather stay right here for
now. (623.3ff)

[Ramana Maharshi] continued to practice his austerities. He became fearfully
thin. His body was smeared with unwashed dirt; his hair, grown again was a
clotted mass, and his nails were so long that he could not use his hands. he
sat for weeks on the floor in deep Samadhi, unconscious of the thousands of
ants that crawled over and bit him. The young Swami's fame increased and the
swarm of pilgrims grew so intolerable that [...] he moved to a mango grove,
which no one was allowed to enter without the owner's leave. Here he stayed
for six months. (from 'The Saint' by S. Maugham)

Maharshi taught that the goal of life is the complete dissolution of
personal identity.
