“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.

The well-being of the Sangha is the comfort of the Sangha. The comfort of the Sangha is for the restraint of bad people. The restraint of bad people is for the ease of good monks. The ease of good monks is for the restraint of the corruptions relating to the present life. The restraint of the corruptions relating to the present life is for the restraint of the corruptions relating to future lives. The restraint of the corruptions relating to future lives is to give rise to confidence in those without it. The giving rise to confidence in those without it is to increase the confidence of those who have it. The increase in confidence of those who have it is for the longevity of the true Teaching. The longevity of the true Teaching is for supporting the training.
