So, too, the mind which is dammed and controlled, trained constantly, will be of immeasurable benefit. The Buddha himself taught, "The mind that has been controlled brings true happiness, so train your minds well for the highest benefits." Similarly, the animals we see around us - elephants, horses, buffaloes, and so on must be trained before they can be useful for work. Only after they have been trained is their strength of benefit to us.
In the same way, the mind that has been trained will bring many times the blessings of that of an untrained mind. The Buddha and his Noble Disciples all started out in the same way as us with untrained minds. But, afterward, look how they became the subjects of reverence for us all. And see how much benefit we can gain from their teachings. Indeed see what benefits have come to the entire world from these men who had 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.
