People think that to prepare for difficulties, you just fortify yourself from the outside. You stock up your house with food, or you just try to take a more defensive position. Or in extreme cases, you act as if you were on the verge of war, and you remove yourself to some distant location far away in the country, you arm yourself, and you look at everything fearfully.
However, the inner preparation is more important than the outer preparation. For you do not know what you are preparing for yet. You cannot tell how things will go. And because you are ultimately here to serve humanity rather than to run away from humanity, you are really not engaging with the truth about your life if you simply try to build security for yourself.
That is why the inner preparation is essential.
