References – AN 4.161: In Brief 
“The Buddha wasn’t tortured like Jesus. Why did he set such high standards to tolerate pain with equanimity (MN 21.20)? Almost impossible to do for a human. Maybe som Tibetan monks can endure Chinese torture in such a detached way.” Answered by Ajahn Pasanno. [Abuse/violence] // [Cessation of Suffering] [Liberation]
