Just as our body becomes accustomed to the taste and flavour of certain foods and craves more of the same, our body also becomes accustomed to the “taste” and “flavour” of certain thoughts, feelings and moods – even those that we view as being negative.
The body/mind complex can become addicted to certain feelings - pleasurable or painful - and then the cells of the body cry out to be fed with more of that emotion and, more often than not, the mind will oblige.
This is how we can become addicted to thinking worrying thoughts, angry thoughts or anxious thoughts which can present as long-term anxiety or depression.
When we think, it triggers our emotions and then chemical messengers (neurotransmitters) carry these messages to every cell in our body. The cells can become addicted to these chemical messages (generated by worry thoughts, angry thoughts, shame thoughts etc.) and want to be constantly fed with them.
The Pain Body
Spiritual teacher and writer, Eckhart Tolle often talks about what he calls the pain body.
The pain body holds all our pain, hurt, hate, anger and also collective human pain. The pain body needs to be fed with emotions such as hurt, anger or hate. So, in order for it to be fed, more emotions like that have to be generated. So, we end up looking for narratives, stories, justifications, reasons to create these emotions to feed the pain body.
He describes thoughts as life forms that we identify with. When we identify strongly with certain thoughts, they create certain emotions that feed the Pain Body.
The pain body is formed of grievances and holding grievances nourishes the pain body.
When we become aware of or our habitual thoughts, when we are not embodying or identifying with them or seeing them as our identity but merely observing them, we manage to separate ourselves from our thoughts. And that is the first step towards releasing our grievances and our addiction to painful thoughts and emotions - the realisation that although you have certain thoughts and emotions, those thoughts and emotions are not you. They are something you have. They are not who you are.
