For all the talk of peace, harmony, and love within relationships of all sorts, people have a strong tendency to forget or to ignore that in order for this harmony to actually occur, then each and every person in everything that they do, should be willing the good of the other, in every interaction so generated. That is to say, there can never be true peace and justice in this world, when one party is getting over on the other, or when one party professes one thing, while doing something other, or if one or both parties behave selfishly at the expense of the other, demonstrated by their attitude and by their actions.
To resolve all of the disharmony and strife in this world, is as straightforward as actually living to the creed, that all are equally entitled to good, and therefore, that the greatest good that we can provide to our fellow brothers and sisters, is to sincerely desire to see that in all that we do, that we are good, and further that in every interaction, that we make it our point, to see that we are good to others, as if we are those others.
Further, to consider it logically, every time that we catch ourselves either thinking or acting out in a manner in which we are directly or indirectly taking advantage of another, we are quite obviously not willing the good of the other. Additionally, those that do not sincerely will the good of the other, are helping to aid and augment the construct that will never allow this world to be a world of peace, harmony, and love because if others are not being good, then the world itself, is not going to be good. It is only when everyone, without exception, is good, can this world be a good world, and therefore, in every circumstance of our lives, we have a sacrosanct obligation to will the good of the other, because that is the true doctrine of good.
So too, while it is correct to get our mind right in its thoughts and by those thoughts to thereby follow through with the right actions; it is never going to be enough to simply will the good of the other, but rather it is vital to do our part to help bring that good will unto others to fruition. While, each of us is entitled to our own free will, and none should be coerced into doing what they do not wish to do, we are all ultimately part of the same world, so that every action has a reaction, in which, our actions or inactions have consequences, so then, where there is disharmony we must do our part to bring harmony, as well as where there is misunderstanding to bring understanding, and also where there is hurt to bring healing.
In summary, we will the good of the other, because that is what we want for others to do for us, and the more good that is done one to another, the more good that there will be, so that, the good that is lacking in this world, comes down to not only whether we are good or not, but also how we propagate that good with those we interact with day-by-day.
