Theoretical exploration of yogic and parapsychological correlations: A Neuropsychological perspective based on teachings of the Haṭha Yoga Pradīpikā

Yogic practices described in the Haṭha Yoga Pradīpikā, such as Prāṇāyāma, Mudrā, Bandha, and Meditation, enhance attentional control, autonomic regulation, and neural integration. These practices parallel neuroscientific findings including vagal modulation through breathing, reduced default mode network activity, and increased gamma synchrony during meditation. Yogic descriptions of heightened intuition and expanded cognition show similarities with phenomena discussed in parapsychology, though these remain debated. Emerging models like predictive processing provide tentative explanations for such experiences. The review highlights significant conceptual overlaps across traditions, suggesting that improved attention and autonomic stability underlie altered states of consciousness, but methodological and epistemological differences require cautious interpretation and further interdisciplinary research.

Abstract

The study of consciousness has been a key focus in both Eastern contemplative traditions and modern science. Yogic texts such as the Haṭha Yoga Pradīpikā (HYP) describe psychophysiological states and experiential phenomena that resemble concepts in parapsychology and neuropsychology. This review aimed to develop a theoretical framework explaining how yogic practices influence consciousness, cognitive processes, and altered states of awareness by integrating yogic, parapsychological, and neuroscientific perspectives. A conceptual review approach was used, systematically examining classical yogic literature, parapsychological studies, and contemporary neuroscientific findings to identify shared principles and mechanisms. Findings indicate that the HYP outlines a structured psychophysiological model where practices such as Prāṇāyāma, Mudrā, Bandha, and Meditation enhance attentional control, autonomic regulation, and neural integration. These practices parallel neuroscientific observations, including vagal modulation through breathing, reduced default mode network activity, and increased gamma synchrony during Meditation. Yogic descriptions of heightened intuition and expanded cognition show similarities with phenomena discussed in parapsychology, though these remain debated. Emerging models like predictive processing provide tentative explanations for such experiences. The review highlights significant conceptual overlaps across traditions, suggesting that improved attention and autonomic stability underlie altered states of consciousness. However, methodological and epistemological differences require cautious interpretation, emphasizing the need for further interdisciplinary research.
