The approach of entering into Psychological Flexiblity helps people live rich and meaningful lives by changing their relationship with difficult thoughts and feelings, rather than fighting against them. This journey can be understood through three core principles: Accepting, Learning, and Engaging.
Psychological Flexibility is Accepting: Creating Space for What Is
Acceptance is not about giving up or resigning yourself to a difficult situation. Instead, it is an active process of allowing your thoughts and feelings to exist without judgment or struggle. This is the opposite of avoidance, a primary source of long-term suffering.
Mindful Acceptance: This involves being present and aware of your internal experiences—your thoughts, emotions, and physical sensations—without trying to change them. It’s like watching a movie of your mind, acknowledging each scene as it passes without getting tangled in the plot.
Willingness: This is the conscious choice to let go of the struggle. When you stop fighting a difficult feeling, you free up a huge amount of energy that can be used for more meaningful actions. This can be a profound shift, moving you from "I must get rid of this feeling" to "I can make room for this feeling and still move forward with my life."
Psychological Flexibility is Learning: Understanding Your Inner World
Once you've made space for your experiences, the next step to acheiving Psychological Flexibility is to learn from them. This involves gaining a deeper understanding of your own mind and how it works, particularly through the process of cognitive defusion.
Defusion from Thoughts: Your mind is a powerful problem-solving machine, but it can also get stuck. Defusion is a technique that teaches you to see your thoughts for what they are—just words, stories, and images—rather than absolute truths. For example, instead of thinking, "I am a failure," you learn to notice, "I'm having the thought that I am a failure." This simple shift can dramatically reduce the power of a negative thought.
Noticing Patterns: This principle encourages you to observe your own behavioural patterns. When do you try to avoid difficult feelings? What are the short-term benefits and long-term costs of those behaviours? By learning to see these patterns, you gain the psychological flexibility needed to make different choices.
