Om or AUM is the most important sound, syllable, symbol which has great spiritual significance not only in Hinduism but also in most religions of the world. AUM is manifesting word of God. AUM is the energy which harmonise our body, mind and soul and connects with Cosmic Consciousness.
AUM represents the whole sound producing system in the mouth which starts from abdomen to heart to head and ultimately connects to cosmic consciousness. Om is the single most important sound that can, by itself, configure the human body optimally for maximum resonance.
The essence and importance of AUM finds mention in various Upanishads and other religious texts of Hinduism. It is a sacred spiritual invocation made before and during the recitation of spiritual texts, during puja, ceremonies of rites of samskara, Meditation and Yoga. It is first syllable to initiate most mantras.
The sound and structure of AUM describes four states of consciousness viz. conscious state, active unconscious state, latent unconscious state and pure conscious state which operates through seven instruments & nineteen channels. The three root syllables of AUM represent three deities, three genders, three Vedas, etc.
OM is sacred in Jainism, & Buddhism, as Omkar in Sikhism, Hum in Tibetans, Ameen in Muslims, Amen in Egyptians, Greeks, Romans, Jews, and Christians.
In a pilot functional Magnetic Resonance Imaging study, the neurohemodynamic correlates of ‘OM’ chanting indicate limbic deactivation. Similar observations have been recorded with vagus nerve stimulation treatment used in depression and epilepsy, the study findings argue for a potential role of this ‘OM’ chanting in clinical practice.
The explanations of AUM, its science, details as per various scriptures of Hinduism and its relevance in other religions are as under:-
Science of AUM
AUM is the basis of all sounds. The first letter, A, is the root sound rises from the belly, lips are parted, pronounced without touching any part of the tongue or palate; the U sound moves from the abdomen into the heart & rolls from the very root to the end of the sounding board of the mouth and the M represents the last sound in the series, being produced by the closed lips which creates a buzzing in the head. Fourth sound fades into nothing. Thus, Om represents the whole phenomena of sound-producing.
AUM in Hinduism
