Integrating mindfulness and subjective well-being therapeutic interventions has become particularly relevant today. The main aim is to theoretically explore, describe and comprehend the concepts of mindfulness and subjective well-being, as well as the therapeutic interventions based on mindfulness.This exploration involves distinguishing mindfulness from other overlapping psychological concepts, and clarifying the significance and consequencesof the absence of mindfulness. Furthermore, we emphasize the multidimensional nature of the subjective well – being and its profound impact when combined with mindfulness practices.
