Another idea that came out of our teleclasses was around the quantity of foods that affect us negatively. Several people mentioned that even though a large quantity of their "negative food" would affect them, they could eat a smaller amount and be fine. But...
I realized as we were discussing it that the "effect" had to be fairly large to be noticed since the effects people discussed were physical such as upset stomach, nausea, headaches, rashes, cramping, etc. The physical is the LAST place something manifests. Once you feel something in the physical, it has already affected you energetically, mentally, and emotionally. The exact order is energy first, then emotional, then mental, and finally physical.
If something affects you in large amounts, it is definitely affecting you in smaller amounts as well. Even a little bit will drop your energy level, thereby affecting your negative well inside of you. The more you feed the negative well in yourself, the harder it is to access your compassionate self.
