See my comment 56. Laz is completely correct. Our minds are basically sponges/recorders; GIGO is the way it works. Of course each mind (and soul) is unique, but the laws of nature are inexorable. One of these laws is that whatever we focus on with our senses, affects our mind and desires, and whatever thoughts we entertain - the ones we focus our attention on, ask to stick around - lead to action.
Will power won’t work very well if we let our senses and mind focus on stuff that will lead to actions that cause harm, to oneself or others.
Think of someone who needs to lose weight, whose tongue is their downfall and eats not only fattening foods, but too much of them. Is it sane for such a person to collect cookbooks, foodie magazines, pore over them, stroll by restaurants and hang around outside, savoring the aromas, etc? Or to just involve him or herself in activities completely away from the food that so attracts them?
Can we not talk about food?
