The sound represents the transcendent primordial sound, from whose vibrations the entire universe arose according to Hindu understanding. It represents the highest concept of God, the formless Brahman, the impersonal world soul. This encompasses the realm of visible phenomena and the realm of the transcendent. Om is the most comprehensive and sublime symbol of Hindu metaphysics and was first used in the Upanishads. Later, Om became the object of mystical meditation as the combination of the three sounds a, u and m. Among other things, it symbolizes the triad of Vishnu, Shiva and Brahma. It corresponds to the states of waking, dreaming and deep sleep. In all Hindu religions it is considered the holiest of all mantras. by Freepik
