We have to do more than Satan does in every way. Let us be devoted to this kind of life, and people will be moved by us and follow us. Thorough preparation is necessary. Jesus had a 30-year period of preparation. If you have enough preparation then your period of practice will be shortened and your period of fighting will be even shorter.
Nothing happens where there is no thought.
If you want to advance your action, you must become a unique person. For that task you must forget sleeping, leisure, love, sightseeing, etc., and devote yourself only to the work. Some risk is necessarily involved in doing any big task. For that occasion you must first train your body. No matter how hungry you may be, you are encouraged to exercise in the morning.
