In contentless experience (sometimes termed _pure consciousness_) there is an absence of mental content such as thought, perception, and mental imagery. The path to contentless experience in meditation can be taken to comprise the meditation technique, and the experiences (“interim-states”) on the way to the contentless “goal-state/s”. Shamatha, Transcendental, and Stillness Meditation are each said to access contentless experience, but the path to that experience in each practice is not yet well understood from a scientific perspective. We have employed evidence (...) synthesis to select and review 135 expert texts from those traditions. In this paper we describe the techniques and interim-states based on the expert texts and compare them across the practices on key dimensions. Superficially, Shamatha and Transcendental Meditation appear very different to Stillness Meditation in that they require bringing awareness to a meditation object. The more detailed and systematic approach taken in this paper indicates that posturally Shamatha is closer to Stillness Meditation, and that on several other dimensions Shamatha is quite different to both other practices. In particular, Shamatha involves greater measures to cultivate attentional stability and vividness with respect to an object, greater focusing, less tolerance of mind-wandering, more monitoring, and more deliberate doing/control. Achieving contentless experience in Shamatha is much slower, more difficult, and less frequent. The findings have important implications for taxonomies of meditation and for consciousness, neuroscientific, and clinical research/practice, and will provide new and useful insights for meditation practitioners.

Shamatha, Transcendental, and Stillness Meditation are said to aim for “contentless” experiences, where mental content such as thoughts, perceptions, and mental images is absent. Silence is understood to be a central feature of those experiences. The main source of information about the experiences is texts by experts from within the three traditions. Previous research has tended not to use an explicit scientific method for selecting and reviewing expert texts on meditation. We have identified evidence synthesis as a robust and transparent (...) method that is suitable for this purpose. In this paper we use evidence synthesis based on expert texts to examine silence/quietness as a feature of the contentless experiences in the three practices. Objective criteria were used to select a sample of 135 expert texts. A database containing the expert descriptions of the meditation techniques and experiences was produced by extracting the relevant material from the publications and coding that material to differentiate individual features. The database, which forms part of the Supplementary Material for this paper, identifies each feature of the contentless experiences referred to in the expert texts, including silence/quietness. Our key finding is that the experts indicate silence/quietness has a particular connection with stillness, and the absence of concepts, mental activity/noise, thoughts, and disturbance. Further analysis leads to the following insights. The silence/quietness reflects the absence of thoughts and sounds, and this fits neatly with a conception of silence/quietness as the absence of internal and external noise. In some cases the terms silence and quietness may also reflect the absence of other disturbances such as non-auditory perceptions, mental images, and negative feelings. That would fit with a conception of silence/quietness as complete calm or absence of disturbance. It is not clear from the expert texts how silence/quietness is distinct from other features such as stillness that also reflect the absence of disturbances. As a separate matter, silence/quietness has connections with all the other features of the contentless experiences, but the closeness of the connections varies. Our work uncovers fine distinctions and ambiguities which lead to new research questions that can be explored in future studies. (shrink)

As scientists advance knowledge of the brain and develop technologies to measure, evaluate, and manipulate brain function, numerous questions arise for religious adherents. If neuroscientists can conclusively establish that there is a functional network between neural impulses and an individual’s capacity for moral evaluation of situations, this will naturally lead to questions about the relationship between such a network and constructions of moral value and ethical human behavior. For example, if cognitive neuroscience can show that there is a neurophysiological basis (...) for the moral appraisal of situations, it may be argued that the world’s religions, which have traditionally been the keepers and purveyors of ethical values, are rendered either spurious or irrelevant. The questions point up broader dilemmas in the interface between science and religion, and raise concerns about the ethics of neurological research and experimentation. Since human beings will still arbitrate what is “moral” or “ethical,” how can religious perspectives enrich the dialogue on neuroethical issues and how can neuroscience enrich dialogue on religion? Buddhist views on the nature of consciousness and methods of practice, especially meditation practice, may contribute to discussions on neuroscience and theories about the interrelationship between consciousness and ethical awareness by exploring the role that karma, intentionality, and compassion play in Buddhist understandings of the interrelationship between consciousness and ethics.

Through a philosophical analysis of realist interpretations of Madhyamaka Buddhism, I will argue that the Madhyamaka is not well represented when it is represented as nihilism, absolutism or as some non-metaphysical alternative. Indeed, I will argue that the Madhyamaka is misrepresented when it is represented as anything; its radical context sensitivity entails that it cannot be autonomously volunteered. The Madhyamaka analysis disrupts the ontic and epistemic presuppositions that consider inherent existence and absolute truth to be possible and necessary, and so (...) the ultimate truth, śūnyatā, is not an absolute truth or ultimate reality. However, I will argue that śūnyatā does qualify as a universal truth and should be understood as a context-insensitive, non-propositional truth in a non-dual dependent relationship with the multitudinous context-sensitive, propositional truths. This analysis will prove helpful in an investigation of those tensions, discernible within Buddhist modernism and the discourse of scientific Buddhism, that arise when Buddhist apologists claim a timeless modernity and a non-hostility with respect to contemporary worldviews. I will argue that apologists can resolve these tensions and satisfy their intuitions of timelessness, but only if they are willing to foreground the crucial distinction between their Buddhist worldview (their context-sensitive propositional truths) and their Madhyamaka attitude towards that worldview (the context-insensitive truth of śūnyatā). I will go on to generalise this result, showing that this Madhyamaka analysis opens up the possibility for frictionless co-operation between any and all worldviews, and that we therefore have a philosophical basis for a workable and sensitive theory of worldview pluralism. I will find it necessary to defend this position by demonstrating that, despite its context-insensitivity, the ultimate truth’s non-dual relationship with conventional truth mitigates against moral and epistemic relativism. I will further substantiate my claim as to the universal truth of śūnyatā by showing that, in Karan Barad’s ‘agential realism’, we find a revealing example of śūnyatā being articulated from within a non-Buddhist context. Thus, I hope to demonstrate some of the good effects of the Madhyamaka message, and show that this message can only be communicated clearly when it is distinguished from the discourses of Buddhism. In this manner, not by giving it a voice but through finding its voiceless authority, I hope to enable the Madhyamaka speak to the West. (shrink)
