Part-I Concept of Cakras And Corresponding Qualities and Part-II Effect of Tibetan Buddhist Mindfulness Meditation (Vipassana) On Heart Rate Variability (HRV) Spectrum

Abstract

Part-I Cakräs are centers of çakti in präëamayä koça that receive and send information and prana çakti, connecting nerves, hormones and emotions. The subject of cakräs as such is very vast. So this report tries to give a brief summary of various aspects of cakräs especially from yogic äsanäs point of view. Part-II The present study was aimed to determine the effect of Tibetan Buddhist Mindfulness meditation (Vipassana) on the heart rate variability (HRV), a specific indicator of autonomic nervous system (ANS) function. The practice requires considerable awareness with expansive relaxation. 14 males of age range 22 to 41 years(mean 29.0 ±5.19)having completed 10 days basic training on Vipassana, participated in this study. The heart rate variability of all the subjects was assessed in two test sessions, which included a period of meditation and control (random) thinking. There was no significant reduction in heart rate during meditation session compared to the base line. During non-meditation random thinking the heart rate decreased in second, third but maximally in the fifth(4.3beats/min) compared to the baseline (paired T-Test).There was no change in the low frequency to high frequency ratio of the heart rate variability spectrum. The heart rate change in non-meditation suggests that the decrease in heart
