Part 11 - Ekadasaka Nipata Pali

(a) There are eleven kinds of destruction any one of which is likely to befall a bhikkhu who reviles the fellow bhikkhus of the community Lack of progress in his efforts, declining from the stage already achieved, tainted and defiled understanding of the Dhamma, being overcome by his own conceit, unhappiness in leading the holy life; liability to commit offences against the disciplinary rules, likelihood of reverting to the household life, likelihood of being afflicted with an incurable disease, likelihood of becoming mentally deranged, dying with a confused mind and likelihood of being reborn in the Nether Worlds (para 6)

(b) There are eleven benefits derived from cultivation and development of loving-kindness, when frequently practised and firmly established One sleeps soundly and wakes peacefully with no bad dreams; one is regarded with esteem by men; is treated with respect by non-humans; is protected by devas, is unharmed by fire, poison or weapons; his mind is easily concentrated, the features of his face are serene, he will die with an unconfused mind, if he does not attain to Arahatship, he will be reborn in the Brahma realm, (para 15)
