Fundamental principle:

Understanding Reality: Recognize that life is a collection of various experiences and emotions, some pleasurable and others painful. By understanding the nature of these experiences, we can better navigate our emotional landscape. 

Moderating Desires: Cultivate the ability to moderate desires, be they material, emotional, or sensory. By reducing unnecessary desires and pursuing simple pleasures, we minimize suffering and increase contentment. 

Emotional Regulation: Develop skills for emotional regulation, including mindfulness, emotion labeling, and distress tolerance. These skills enable individuals to manage and balance their emotional reactions, leading to improved well-being. 

Acceptance and Change: Embrace the dialectical philosophy of accepting what is and simultaneously striving for change. Acceptance of the present moment and one's emotions is essential for emotional regulation, but it should coexist with a commitment to personal growth and change.
