Om is a symbol of holy sound and spiritual in Hinduism. Om is part of the statue in ancient and medieval ages manuscripts, temples, monasteries and spiritual texts in Hinduism, Buddhism and Jainism. All Indian religions have a spiritual meaning, but the meaning of Om is different between different traditions.
In Hinduism, Om is one of the most important spiritual symbols (Pratima). It refers to the soul (soul, within itself) and Brahma (Ultimate reality, entirety of the universe, truth, divine, supreme soul, cosmic principles, knowledge). In the beginning and end of the chapters of the Vedas, Upanishads and other Hindu texts, Om is called. During worship, during the formulations such as marriage ceremony, sacramental ceremony, meditation and yogic activities, Om is written and spoken first, in the middle and in the end, Om is a sacred spiritual mantra.
It is said that the sound of the ‘OM’ is always echoing throughout the universe. The sound of Om is also experienced from inside the Sun. Om is the nectar which can only be experienced.
What is ‘OM’
‘OM’ does not have any meaning in the actual form. Literally Om is not the word. The word is made in creation and everything from creation, because all creation is in Om, so Om can not be known. Only experience can be done and Om will be experienced only when there is no thought, no desire, no dream, no expectation and the mind is completely calm. Om can not be created, nor has it been done because the creation of the universe itself has been done by Om.
Actually, Tridev (Lord Brahma, Vishnu and Mahesh) and Om are not different. But the word "Om" means the origin of the three gods. All errors, mental distortions can be corrected by the chanting of the om, and the glory song can also be done by Om. Therefore, the Om is preceded by the three Gods. If Om is spoken by true mind and concentration, then the experience of the three gods can be simultaneously and in one place.
