What does the om or aum symbol mean to you?
The most powerful and the significant one is the single-syllabled incantation called the Pranava. This is the OM. The available literature upon the significances of the Vedic mantra is almost voluminous. Nowhere in the world can we meet with a more sacred symbol that has got such a vast amount of significance. From Vedic times until the present day the word ‘OM’ has been taken as a symbol and as an aid to meditation by spiritual aspirants. It is accepted both as one with ‘Brahman’ and as the medium, the Logos, connecting man and God. The entire history of the syllable is in the revelations of the Vedas and in the declarations of the Upanishads. The sound of OM is also called ‘Pranava’, meaning, that it is something that pervades life, or runs through prana or breath. Speaking of OM, the Taittiriya Upanishad says: “Thou art the sheath of Brahman.’ That is, OM is the container for the Supreme and, therefore, invoking OM is invoking the Supreme.
