Abstract: Pranayama practices are being used since ancient times as a holistic approach by saints and yogis to improve and control the subtle phenomenon of the brain and hence to bring mind and body in synchrony using breath as a link. This work is an attempt to understand this subtle phenomenon of the brain and the process of attaining higher state of cognition followed by consciousness. From the Electroencephalogram (EEG) signal analysis, it was observed that with the increase in Pranayama practices, the frequency of oscillation shifts from lower-frequency range to higher-frequency range with the significant rise of gamma power (>40 Hz) in frontal, central and also some part of temporal region of the brain. This frequency shifts count for attaining higher cognitive states leading to consciousness of human brain.
