Brihat-Sanyasa Upanishad

It is one of the sannyasa(Renunciation) Upanishads. Brihat-Sannyasa is notable for its six categories of monks, their begging habits and its manual-like list of who do not qualify to join the order of monks in a monastery.The disqualified from monasteries, according to Brihat-Sannyasa Upanishad, include criminals (homicide), people suffering from contagious diseases such as consumption (tuberculosis), crippled, alcoholics, eunuchs and others.However, states the text in verse 251, that these people may renounce, on their own, when in mortal danger.
