The soul is the the whole package. Inside are the heart, the mind and the body. It’s like one of those Russian dolls that have a smaller one inside, and then another and another. Inside the heart is the will. Inside the mind are thoughts. Also inside thoughts are feelings. Inside thoughts are emotions. We can set all these dolls out on a table and then we need to deal with each one. Our task, as humans, as different from animals, is to be less instinctive. We react to emotions without involving our mind. We need to think better thoughts and use our reasoning ability. We want to gratify our body and so we make wrong choices. Instead, we need resolve to do what is right and that is our will.
