I cannot seem to get a handle on my emotions. I feel sad or angry and it feels like a cloud around me. I thought love was an emotion; how do emotions correlate with the Infallible Way?

The cloud you see in front of you is your resistance to Truth. Those breaks create the experience that evokes sadness or anger. The feelings are part of your experience that helps you identify the state of mind that causes it. It is present for one reason and that is for you to identify and repair the breaks. Once repaired, you completely surrender all separateness until liberation becomes your consciousness. You are free in Truth.
A widespread belief has become that love is an emotion. Emotions are thoughts you place on feelings. For an example, consider the man that robbed at gun point. He was fearful every time he encountered a stranger. His emotion was the thought of being robbed and the fear that it evoked. That emotional response is an
experience. By identifying and repairing the break, fear transforms to Love.
Love is deep caring that exists within you once you transform resistance to the Self. The connection between Love and emotion is that unconditional Love is the power of the Infallible Way upon which experiences (i.e., such as your emotions) manifest. Since you are affected, they represent your needs to identify and repair the breaks in mind and realize your Truth.
Once you have a deep realization that you are the Whole, you genuinely Love the Whole. As it relates to your immediate world, it extends to the community, and the world, at large. With the vastness of love, you are alive at the gateway of heart that originates from the Self. There is only Self as you realize the limitless and boundless capacity of all you ARE! One by one, we make a difference.
