Moreover, whatever makes our heart blossom and whatever causes us unrest, one must reflect on these matters and steer them along the right path. Otherwise, left on a crooked path, one will have to keep wavering and roaming like a crazed monkey that does not know which way to go. If many people in the world today are subjected to many kinds of pain and fall into unrest, one should understand that the cause of all of it is that they do not use the senses along the right path. There is no other cause for unrest to come. One must inquire carefully what comes and goes through each gateway. When, by the path by which one thing comes, another enters, just then unrest and agitation begin in that house. Rather than inquiring after it has come, taking care beforehand is the best way. Well then, even if one has once lost the way, one must see to it that such a mistake does not happen at least the second time. That is the middling way.
