Human thought has tremendous potential. When we concentrate our thoughts on something and really imagine it to be, we can actually force the thing to happen.
To accomplish this, we must visualize every step of the desired result in great detail. Diffused and generalized thought will not work.
But when every faculty of the mind is intensely focused on that which we wish to see happening, we can genuinely exert great influence on all sorts of matters in the world (Rabbi Nachman’s Wisdom #62).
