The science of the Vedic sacred formulae. (Glossary for the Vahinis)
The Mantra Shastra (ancient scripture related to sacred formulas) has laid emphasis on the letter ‘Om’. Omkara has no form. It is the manifestation of Brahman as sound. It is present in all creation. It is effulgent. It is in all speech. It is ever blissful. It is Parathpara-mayi (embodiment of the Supreme). It is Mayamayi (the repository of illusory power). It is Shrimayi (embodiment of prosperity). The Omkara is the only sound that has these eight divine attributes, according to the Mantra Shastra. (SSS Vol.17, pp. 163-164)
