“Non-attachment is a subjective quality characterized by a relative absence of fixation on ideas, images, or sensory objects, as well as an absence of internal pressure to get, hold, avoid, or change circumstances or experiences. The non-attached state of mind is equanimous, flexible, and receptive. This is in contrast to a grasping, anxious, needy, or rigid state of mind. Notably, the concept of non-attachment is related to secure attachment in Western psychological terms (e.g., closeness, allowing others to be as they are, without manipulation, neediness, or judgment) (Sahdra, Shaver, & Brown, in press). Across several studies, the NAS has shown excellent psychometric properties…. Correlational studies have show that the NAS taps a unique quality of consciousness that is related to a variety of cognitive, emotion regulation, interpersonal, well-being, and mental health phenomena.”
