 This was termed the madmans leave ("ummattakasammuti") The texts also assume that this 'madness' can be cured or recovered from, or is at least an impermanent phenomenon, after which, during confession, the monk is considered sane by the sangha once more.There are also stories of lay folk who show abnormal behavior due to the loss of their loved ones.Other Buddhist sources such as the Milinda Panha echo the theory that madness is caused mainly by personal and environmental circumstances.
