Because being mindful is an ancient tradition, it needed to be redefined much more recently to fit in with a Western view of psychology. There have been multiple definitions that psychologist have put forward, including the simple idea that being mindful is about developing wisdom through self-knowledge. For others, mindfulness is a mental strategy that tries to take the emotion out of the moment so that more rational decisions can be made. And yet, being mindful of one's emotions does not necessarily mean that we do not feel them. Some psychologists define being mindful as the practice of meditation itself, while others see it more as a state that people try to maintain through their meditative practices. There again, others think of it as a trait that is akin to aspects of someone's personality. Therefore, although there is little common ground on the subject, most psychologists would agree that how mindful, or otherwise, someone is can be scored on a scale. Needless to say, psychologists around the world have numerous different scales they use with little standardisation among them.
