The exploration of consciousness is a central theme in both Buddhism and Sanathana Dharma (Hinduism) philosophies, and modern scientific inquiry has begun to intersect with some of these ancient concepts. While there are parallels, there are also significant differences in the methodologies, foundational assumptions, and goals of spiritual traditions and scientific inquiry. The intersections, however, provide fertile ground for scientific enrichment.
Nature of Consciousness and Quantum Physics. Both Sanathana Dharma and Buddhism assert that consciousness isn't a byproduct but a fundamental aspect of reality. This perspective aligns, to some extent, with certain interpretations of quantum mechanics, which propose that consciousness plays a role in the process of quantum measurement or wave function collapse.
Meditation, Mindfulness, and Neuroscience: Neuroscientific research into the effects of meditation—a practice central to both Sanathana Dharma and Buddhist traditions—has shown that it can induce significant changes in areas of the brain associated with attention, emotion regulation, and self-awareness.
Self and Non-self: Sanathana Dharma philosophy's exploration of the self through concepts like "Atman" (individual soul) and its relationship with "Brahman" (universal consciousness) can be seen in parallel with the scientific exploration of individual consciousness and its relationship with the world. Buddhism's concept of "Anatta" (non-self) proposes that there's no continuous, unchanging self. This idea resonates with certain findings in neuroscience, suggesting that the perception of a continuous "self" is an emergent property of various neural processes and not localized in one part of the brain.
Levels and States of Consciousness: The Mandukya Upanishad, outlines different states of consciousness, including waking, dreaming, deep sleep, and a transcendent state known as "Turiya." Modern neuroscience also explores various states of consciousness, such as REM sleep, deep sleep, and altered states induced by substances or meditation. Buddhist meditation practices often aim to transcend ordinary states of consciousness and attain enlightened states. Neuroscientific studies on accomplished meditators have reported unique brainwave patterns and states of consciousness.
Interconnectedness: Both Sanathana Dharma and Buddhist philosophies emphasize the interconnectedness of all things. This idea has resonances with holistic perspectives in science, especially in fields like ecology and certain interpretations of quantum physics which emphasize non-locality and entanglement.
Plasticity and Transformation: Both Sanathana Dharma and Buddhist traditions emphasize the possibility of transforming one's mind and consciousness. The idea of neuroplasticity in modern neuroscience—that the brain is malleable and can be changed through experiences, especially practices like meditation—aligns with this.
Phenomenal Experience: Buddhism, particularly in schools like Yogacara, delves deep into the nature of experience, cognition, and perception. These explorations find parallels in cognitive science and phenomenological approaches in modern philosophy of mind.
