Summary
AI-generated from the abstractTheta brainwave power increased across all brain regions during 30 minutes of Om mantra meditation, indicating deep relaxation. Both Fourier and wavelet analysis of EEG signals showed the same pattern of increased theta power, confirming the meditation's relaxation benefit. The authors suggest that daily practice of this 30-minute meditation could serve as a de-stressing routine.

Abstract
In our previous study, FFT analysis has been used for spectral analysis of the EEG signal to investigate the effect of Om mantra meditation. It was proved that this mediation plays a role in providing relaxation. In the present study, we continued our work with wavelet analysis to firmly establish this benefit. Two-way repeated measures ANOVA was used on relative power obtained by FFT and DWT. The comparative results of both methods are presented. The same increasing and decreasing pattern of relative power are observed in each band with FFT and DWT. An increase in theta power in all regions of the brain has been observed with both the methods. Raised theta is a sign of deep relaxation. The study confirms that this 30 minutes of Om mediation offers relaxation; then it could be the way to de-stress if adopted as a daily routine.
