Impact of Mahā Mantra Chanting on Electroencephalogram Signal Rhythms Functions to Reduce Anxiety and Depression of Individual

Hare kṛṣṇa hare kṛṣṇa kṛṣṇa kṛṣṇa hare hare hare rāma hare rāma rāma rāma hare hare is the Mahā Mantra (MM). The Mantra is believed to be the sacred mantra from the ancient times. In the current research, an attempt has been made to study the brain dynamics of oscillatory changes after MM chanting. The mantra chanting produces a state of mind that has a positive effect on the individual’s brain. The electroencephalogram (EEG) signals are asynchronous in nature and record the brain's present state. In this study, forty individuals were assigned randomly into two (pre &post) groups,(n=20) with equal ratio of male and female and having mean age 25.5yr, EEG signal was recorded in eyes closed condition both prior as well as after the MM chanting. The rhythms (Delta, theta, alpha, beta, and gamma) were extracted from the recorded EEG signals using the Fourier-Bessel series expansion (FBSE) based rhythms method. To match the behavioural changes in the nature of the EEG, the power of the rhythm was computed and compared. According to the study, following MM chanting, the central and parietal regions of the brain had an increase in alpha relative power, which indicates that the brain has been refreshed and relieved. The study showed generous production of alpha, theta and delta waves which has been found in the study to be associated with the secretion of hormones or neurotransmitters causing dilation of blood vessels. Results revealed an increase in the carbon levels and at the same time a decrease in carbon dioxide and lactic acid levels leading to less anxiety, disappointment, nervousness, irritation, and anger.
