Appearances in Koans
Hara is featured in several koans. He was well known for his disregard of many of the precepts of everyday Buddhism, such as dietary laws.
The Muddy Road
The following is one of the most famous stories of Tanzan.
:Tanzan and Ekido were once traveling together down a muddy road. Heavy rain was falling. As they came around a bend, they met a lovely girl in a silk kimono and sash, unable to cross at an intersection.
:"Come on, girl," said Tanzan at once. Lifting her in his arms, he carried her over the mud.
:Ekido did not speak until that night when they reached a lodging temple. Then he could no longer restrain himself. "
We monks don't go near females," he told Tanzan, "especially not young and lovely ones. It is dangerous. Why did you do that?"
:"I left the girl there," said Tanzan. "Are you still carrying her?"
A Buddha
In Tokyo in the Meiji era there lived two prominent teachers of opposite characteristics. One, Unsho, an instructor in
Shingon, kept Buddha's precepts scrupulously. He never drank intoxicants, nor did he eat after eleven o'clock in the
morning.
The other teacher, Tanzan, a professor of philosophy at the Imperial University, never observed the precepts. When he
felt like eating he ate, and when he felt like sleeping in the daytime he slept.
One day Unsho visited Tanzan, who was drinking wine at the time, not even a drop of which is supposed to touch the
tongue of a Buddhist.
'Hello, brother,' Tanzan greeted him. 'Won't you have a drink?'
'I never drink!' exclaimed Unsho solemnly.
'One who does not drink is not even human,’ said Tanzan.
'Do you mean to call me inhuman just because I do not indulge in intoxicating liquids!' exclaimed Unsho in anger. Then
if I am not human, what am I?'
'A Buddha.' answered Tanzan.
