Take the subjective ‘good’ with the subjective ‘bad’. Recognise that all merely is, and that as events occur their objective meaning is to merely be, it is only we as the ego for whom decide what is moral, for what is ‘good’ and what is otherwise. Such that we could say that all is as it should be and it is only the foil of the human that they be set to defy the past and predict the future only to be surprised. Accept the whole, and move from duality, for a world that sits in duality is a world quite literally divided, and within that, the destruction of either side means the destruction of the other. So then, to bring peace, a warrior must accept the whole and fill themselves with peace. For a nation in which every dividual has peace in their hearts, is a nation sitting in peace. How to apply realistically? Recognise that all actions that one takes has the chance to provide the expected outcome, that there is a chance in the universe that the 600th time you drop an apple, it actually floats upward. So, this is to say that all actions and events have the chance to be everything different, and for that we have only the control on our inputs and get to experience the wonder of life: consequences.
Meditate.
