  Five types of primordial wisdom: describe the enlightened mind. They include primordial awareness of dharmadhātu, mirror-like awareness, primordial awareness of equality, discriminating primor-dial awareness and the primordial awareness that accomplishes all actions.

  Frontal lobes: large areas of the brain located in the frontal parts of the two brain hemispheres; their functioning mediates complex mental processes including planning, decision making, working memory, attention control and monitoring, and coordination of complex movement.

  Functional magnetic resonance imaging (fMRI): brain imaging method based on metabolic changes in the blood (blood-oxygenation-level-dependent (BOLD) signal) in response to cognitive demands. This method has very good spatial resolution (in terms of millimetres), but relatively poor timing specificity.

  Grey matter of the brain: mainly contains brain cell bodies and receptive branches of neurons.

  Hedonistic happiness: derived from pleasure, typically short-lived and bound to particular pleasurable stimuli or circumstances.

  Insula: area in the cortex of the brain involved in awareness of emotions and sensations in the body.

  Introspection: method of exploring the mind based on observation of our own mental processes.

  Mahāyāna: set of Buddhist teachings emphasizing the Bodhisattva ideal which are predominant in Tibet, China, Vietnam and Japan.

  Meta-awareness (Pāli: sampajañña; Sanskrit: samprajanya; Tibetan: shizhin): the monitoring element of attention, which checks the quality of focus on the object of meditation and notices distraction.

  Metacognitive self-regulatory capacity of the mind (MSRC): a natural propensity of the mind which enables introspective reflective awareness of mental processes and behavior, and is a necessary pre-requisite for effective self-regulation supporting well-being. It consists of interacting systems and processes of metacognition and attention, emotion regulation and conceptual processing.

  Mindfulness (Pāli: sati; Sanskrit: smṛti; Tibetan: trenba): in the Buddhist context it is a faculty of the mind which enables the practitioner to sustain attention on the object of meditation; in Buddhism mindfulness is associated with prospective memory – remembering to pay attention to the object of meditation. In secular approaches mindfulness is described more broadly as non-judgmental awareness focused on the present moment.

  Mindfulness-based approaches: a group of secular programmes and therapeutic approaches in which mindfulness is the central component; these most notably include mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT). There are other approaches such as dialectic behaviour therapy and acceptance commitment therapy in which mindfulness is a therapeutic element.

  Mindfulness-based cognitive therapy (MBCT): an eight-week secular programme combining mindfulness training with elements of cognitive behavioural therapy; MBCT was specifically developed for treatment of recurrent depression.

  Mindfulness-based stress reduction (MBSR): an eight-week secular programme developed by Jon Kabat-Zinn which involves a variety of mindfulness practices, education about stress, group discussions about conscious experience and yoga-based practices. The MBSR laid the foundation for other mindfulness-based approaches.

  Modes of existential awareness (MEA): overarching, phenomenologically distinct, state shifts in the awareness of self and reality; they are enabled by cumulative changes in the metacognitive, attentional, affective and conceptual aspects of the MSRC modulated by motivational/intentional and contextual factors of meditation practice.

  Mood: in comparison to emotions a more general emotional state lasting for days or weeks.

  Neural plasticity: describes the modifiability of neural connections, and more broadly brain function and structure, by experience.

  Orbitofrontal cortex (OFC): area in the prefrontal cortex of the brain involved in decision making and particularly in reward-related processing imbalance, which may contribute to development of addictions.

  Ordinary mind: in the context of Dzogchen one of the three levels of consciousness which includes sensations, perceptions, thoughts, memories and affect we typically experience and can mostly become aware of if we observe the mind. These mental processes enable us to learn new skills, make decisions and function efficiently in everyday life.

  Precuneus: a brain structure implicated in conscious experience.

  Prefrontal cortex: the most frontal part of frontal lobes of the brain excluding motor cortex of the frontal lobes.

  Pristine awareness (Sanskrit: vidyā; Tibetan: rigpa): in Dzogchen it is the most subtle aspect of consciousness; the final goal of Dzogchen practices is to access and experientially recognize this type of consciousness and sustain awareness at this ever-present level of ultimate mental balance.

  Self-regulation: the ability to notice and effectively manage thoughts, emotional responses and behavior; typically described as consisting of attention regulation and emotion regulation.

  Shamatha (Pāli: samatha, Sanskrit: śamatha or shamatha; Tibetan: shyiné): aspect of Buddhist mind training concerned with cultivation of stability, monitoring and redirecting qualities of attention; sometimes referred to as calm abiding.

  Substrate consciousness (Sanskrit:ālayavijñāna; Tibetan: kun gzhi nams shes): the second out of the three layers of consciousness described in the Dzogchen tradition. This layer of consciousness contains more subtle tendencies of behaviour, mental habits and temper which influence the ordinary mind. It contains the roots of mental frameworks which underlie our construed notions of ‘self’ or ‘I’.

  Theravāda: considered the oldest school of Buddhism and predominant in Southeast Asia.

  Vajrayāna (Tantrayāna): a branch of Buddhism prevalent in Tibet which focuses on practices involving sacred visualizations, mantra recitation and work with energies of the body.

  Valence: places an emotion on a scale from positive to negative (pleasant to unpleasant).

  Vipassana (Pāli: vipassana; Sanskrit: vipasyana; Tibetan: lhaktong): practices in which the meditator watches as thoughts, perceptions and emotions arise and fade away, and gradually explores the source of mental activity and its characteristics.
