In this case study, we describe the experience of a short-duration meditation method called mind-body relaxation and rejuvenation technique (MBRRT), inspired by the ancient mālā japa. A middle-aged person practiced it for a period of two and a half years. During the MBRRT performance, the experience in terms of sleep was collected through a self-report proforma for 60 practice sessions. It was...
Heart rate variability (HRV) signals provide a non-invasive way of analyzing the functioning of the autonomic nervous system (ANS), providing important information on how mental states affect the body. This study focused on how HRV features change during meditation compared to pre-meditation states. In this work, we propose analysis of HRV signals using nonlinear features including the...

Abstract In this study, we are implementing an easy technique of coordination between breathing and thumb movement on finger divisions, which is performed with closed eyes for a short duration of five minutes. This technique has been practiced by a small group of 28 participants in a natural classroom setting and its immediate impact on calming down and inducing sleep was observed distinctly (p...
INTRODUCTION: In recent times, an upsurge in the investigation related to the effects of meditation in reconditioning various cardiovascular and psychological disorders is seen. In majority of these studies, heart rate variability (HRV) signal is used, probably for its ease of acquisition and low cost. Although understanding the dynamical complexity of HRV is not an easy task, the advances in...
In this paper, we propose a textural information-based analysis of scalogram image obtained from continuous wavelet transform of heart rate variability (HRV) signal to study its dynamics during meditation. In addition to features from scalogram image, visibility graph-based complexity measures and multiscale permutation entropies (MPEs) from HRV signal are used to elucidate the modulation in...
