Spectral Analysis of Vishnu Sahasranama: Effects on Stress Levels and Memory Improvement

The use of mantra chanting has been an integral component of spiritual and contemplative traditions for centuries and has increasingly attracted scientific interest due to its potential effects on psychological well-being and cognitive functioning. Among these sacred texts, the Vishnu Sahasranama—a collection of one thousand names of Lord Vishnu—is widely recited for spiritual growth, mental tranquility, and emotional stability. Despite its cultural and religious significance, limited research has examined its neurophysiological and cognitive implications using modern analytical techniques. This chapter investigates the spectral characteristics of the Vishnu Sahasranama and explores its influence on stress reduction and cognitive enhancement. A comprehensive review of relevant literature was conducted to examine the historical, spiritual, and scientific perspectives associated with mantra chanting. In addition, electroencephalography (EEG)-based spectral analysis was employed to evaluate brainwave activity during mantra recitation, focusing on frequency-domain changes associated with relaxation, attention, and memory-related processes. The findings indicate that the rhythmic and repetitive structure of the Vishnu Sahasranama is associated with measurable alterations in neural oscillatory activity. Increased alpha and theta band activity was observed during chanting, suggesting enhanced relaxation, reduced stress, and improved attentional control. Furthermore, the synchronization of specific brainwave frequencies appeared to support memory retention and cognitive processing. These observations are consistent with previous studies reporting beneficial effects of meditative chanting on emotional regulation and cognitive performance. The chapter concludes that spectral analysis provides valuable insights into the neurophysiological mechanisms underlying mantra chanting and its potential role in promoting mental well-being. The results highlight the relevance of integrating traditional spiritual practices with contemporary neuroscience and suggest future research directions involving multimodal neuroimaging, larger participant cohorts, and longitudinal investigations to better understand the therapeutic applications of mantra-based interventions in psychology, cognitive science, and music therapy.
