The emerging neuroscience literature has provided some evidence that meditation may have measurable effects on the electrophysiological parameters in the nervous system. We hypothesized that a novel geometric meditation approach comprising Geometric Somatic-Breathing Based (GSBB) and Geometric Introspective Based (GIB) meditation yield favorable electrophysiological changes at brain's cortical level and autonomic nervous system upon deep meditative experience. Materials & Methods:A multi-sensor digital sampling setup, including Electroencephalography (EEG), Galvanic Skin Response (GSR), and Heart Rate Variability (HRV) was used to obtain data and compare meditation and baseline epochs from 3 long-term geometric meditators. Results:The analysis revealed a notable change in autonomic nervous response, including Root Mean Square of Successive Differences (RMSSD) in Heart Rate Variability (HRV) as well as GSR and Quantitative Electroencephalogram (QEEG) correlates across 10 practiced techniques in training and post-training as compared to the baseline state. Conclusion:Such findings may serve as a pilot validation dataset to pursue further research on quantitative EEG-guided geometric meditation approach.

Obsessive-Compulsive Disorder (OCD), characterized by unwanted and distressing intrusive thoughts, images, urges, doubts and ideas or sensations and repetitive mental or behavioral acts, which is regarded as an overwhelming mental disorder. Over the past few years, several studies have indicated how mindfulness-based interventions may be effectively used to remediate OCD symptoms based on which such methods are endorsed as effective complementary or alternative options to remediate OCD. The present pilot investigation assessed the effectiveness of Geometric Meditation-based Cognitive Behavior Therapy (GM-CBT) as a novel integrated approach to help OCD symptoms. Accordingly, an eight-week treatment program (90 minute sessions per week) in a single case of intractable OCD was found to result in a significant reduction in OCD symptoms, anxiety and depression as well as increased mindfulness skills and subsequent secondary outcomes. A three-month post treatment follow up suggested longlasting beneficial effects. Such a pilot model may receive further endorsement as a holistic CBT approach for OCD.
