<b style="">Spectral analysis of the Vedic mantra Omkara</b>

154-161 It has been recognised for quite some time that Mantras or sacred words have beneficial effects on human beings and even plants. In a previous study, the authors have demonstrated the effect of Agnihotra mantra chanting at sunrise and sunset on the germination of rice seeds. Scriptures also mention that mantras like Om, Gayatri and Mrityunjaya have benefited humanity quite a lot. This paper is an attempt to identify quantitatively the signal characteristics of mantra sound patterns. It is a pilot study and appears to be one of the first of its kind in the world. The study has confined itself to the identification of the predominant frequencies and their subharmonics of A-kara, U-kara, Ma-kara and Om-kara.
