Comprehensive Review of the Cognitive and Therapeutic Effects of Mantras

Abstract

Mantra, a spiritual and cognitive practice, has gained significant attention in contemporary scientific discourse due to its potential mental health benefits. This review consolidates existing research on the effects of mantra chanting, particularly its influence on cognitive function, emotional regulation, and physiological well-being. Studies indicate that mantra enhances mindfulness, reduces stress, and improves cognitive flexibility, with neuroimaging data suggesting increased alpha and theta wave activity during practice. The impact of mantra is particularly relevant in academic settings, where students face heightened stress levels. Empirical evidence from EEG-based research demonstrates a reduction in pre-examination anxiety and an enhancement in cognitive processing efficiency following mantra chanting. Furthermore, ancient Vedic practices such as Yagya and Vishnu Sahasranama chanting have shown promise in therapeutic applications, influencing both neurological and physiological health markers. Current research utilizes Convolutional Neural Networks (CNNs) with Long Short-Term Memory (LSTM) models to analyze EEG signals for validating the stress-management effects while improving brain cognition from mantra. The recognition of mantra effectiveness is solid yet researchers need larger standardized studies and more consistent experiment design with adequate participant numbers to validate these results. Research into mantra-based interventions needs to involve continuous EEG observation in combination with state-of-the-art neurocomputational methods and tracking participant progress through time. The combination of traditional wisdom with modern scientific methods makes mantra a valid and whole-systemic method to build mental strength and cognitive health.
