The Buddha and his noble disciples all started out in the same way as us – with untrained minds; but afterwards look how they became the subjects of reverence for us all, and see how much benefit we can gain through their teaching. Indeed, see what benefit has come to the entire world from these men who have gone through the training of the mind to reach the freedom beyond. The mind controlled and trained is better equipped to help us in all professions, in all situations. The disciplined mind will keep our lives balanced, make work easier and develop and nurture reason to govern our actions. In the end our happiness will increase accordingly as we follow the proper mind training.
