Mindful meta-awareness: sustained and non-propositional.

Meta-awareness appears to be essential to nearly all forms of mindfulness practice, and it plays a key role in processes that are central to therapeutic effects of mindfulness training, including decentering - shifting one's experiential perspective onto an experience itself - and dereification or metacognitive insight - experiencing thoughts as mental events, and not as the things that they seem to represent. Important advances in the conceptualization of meta-awareness in mindfulness have recently been made, yet more clarity is required in order to characterize the type of meta-awareness implicated in the ongoing monitoring of attention and affect, even while attention itself is focused on an explicit object of awareness such as the breath. To enhance research on this form of meta-awareness cultivated in at least some styles of mindfulness, a construct of sustained, non-propositional meta-awareness is proposed.
