“OM” meditation is a form of meditation that involves the repetition of the word “OM”. The utterance of “OM” consists of three letters: A, U, and M. “OM” is considered a sacred sound in Hinduism, Buddhism, and Jainism and is often chanted at the beginning and end of Hindu and Buddhist prayers and mantras. The syllable “OM” is the sound of the universe, representing the energy and vibration of all things. It is believed to be the primordial sound from which all other sounds and the universe were created [1]. According to “Mandukya Upanishad”, “OM” (AUM) denotes four states of human consciousness: the first is “Jagrat”, which indicates “A” of AUM; in this state, consciousness is turned outward to the external world. The second state is “Swapna”, which indicates “U” of AUM; in this state, consciousness is turned towards the inner world. The third state is “Prajna”, which indicates “M” of AUM; in this state—an unconscious state—the deep impressions of the mind are stored here in their latent form, like a seed. The final state is “Turya”, which indicates pure consciousness. It permeates and observes the other three states; from the vantage point of Turya, one sees the entire play of the levels of consciousness [2]. “OM” meditation typically involves sitting comfortably in a quiet place, closing the eyes, and focusing on the sound of the “OM” as it is repeated either aloud or silently. The practitioner focuses on the sound and vibration of the “OM” mantra, allowing it to resonate throughout the body and mind. The repetition of the sound is meant to help calm the mind and bring the practitioner into a state of deep relaxation and inner awareness [3].
