The ten reasons for the laying down of training rules
“The Buddha laid down the training rules for his disciples for ten reasons: for the well-being of the Sangha, for the comfort of the Sangha, for the restraint of bad people, for the ease of good monks, for the restraint of the corruptions relating to the present life, for the restraint of the corruptions relating to future lives, to give rise to confidence in those without it, to increase the confidence of those who have it, for the longevity of the true Teaching, and for supporting the training.
