What is Aum?
Aum (Sanskrit: ॐ), more commonly transliterated as Om, is the sacred syllable considered the sonic representation of ultimate reality in Hindu, Buddhist, and yogic traditions. It is both a mantra—a sound used in meditation and ritual—and a symbol of the Absolute (Brahman). The syllable is traditionally understood as encompassing all states of consciousness: waking (A), dreaming (U), deep sleep (M), and the silence that follows, representing the transcendent fourth state (turiya). Aum is chanted at the beginning and end of yogic practice, Vedic recitation, and contemplative rituals, serving as an anchor for awareness and an invocation of the sacred.
Origins & Lineage
Aum first appears in the Vedic texts, the oldest layer of Hindu scripture dating to approximately 1500–1200 BCE. The Mandukya Upanishad (circa 800–500 BCE) offers the most influential exegesis, interpreting Aum as the sound-form of Brahman and mapping its three phonemes (A-U-M) onto the four states of consciousness. The Yoga Sutras of Patanjali (compiled circa 400 CE) describe Aum as the verbal expression of Ishvara (the divine) and recommend its repetition (japa) as a method for attaining samadhi. The syllable is central to both Shaiva and Vaishnava traditions, and is embedded in longer mantras like “Om Namah Shivaya” and “Om Namo Narayanaya.” In Buddhist traditions, particularly Tibetan Buddhism, Aum forms the opening syllable of the mantra “Om Mani Padme Hum” and is understood as the sound of enlightened body, speech, and mind.
How It’s Practiced
Aum is most commonly practiced as a standalone chant or as the opening invocation in mantra meditation. Practitioners typically sit in a comfortable meditation posture, take a deep inhalation, and intone the syllable on a slow, sustained exhale. The sound is often elongated, with emphasis on the three phonetic components: “Ah” begins in the belly, “Oo” resonates in the chest, and “Mm” vibrates in the head, followed by silence. The practice can be performed aloud, whispered, or mentally (manasika japa). In group settings, particularly yoga classes and kirtan, Aum is chanted in unison to synchronize energy and intention. It is also inscribed or visualized as the symbol ॐ during meditation to deepen concentration.
Aum Today
Today, Aum is ubiquitous in yoga studios, meditation centers, and mindfulness programs worldwide. It opens and closes asana classes in styles ranging from vinyasa to kundalini, and is featured in sound baths, mantra concerts, and chant recordings by artists like Deva Premal and Krishna Das. Seekers encounter Aum in residential retreats, particularly those rooted in advaita vedanta, vipassana, and hatha yoga. The syllable has also entered secular wellness spaces, sometimes stripped of its theological context and presented simply as a “vibrational reset.” Sacred sites in India—Rishikesh, Varanasi, and the ashrams of Ramana Maharshi and Sivananda—remain pilgrimage destinations for those wishing to study Aum in its traditional setting.
Common Misconceptions
Aum is not a deity to be worshiped, nor is it a generic “positive vibration” divorced from lineage and meaning. While some New Age contexts treat it as interchangeable with other sacred sounds, Hindu and Buddhist teachers emphasize that Aum carries specific theological weight: it is the name of Brahman, not merely a relaxation technique. The spelling “Aum” reflects the three Sanskrit phonemes more precisely than “Om,” though both are acceptable. Chanting Aum does not require adherence to Hinduism or Buddhism, but respectful engagement with its origins is encouraged. Finally, Aum is not a magic formula; its power, according to tradition, emerges from sustained practice, right intention, and understanding.
How to Begin
Begin by listening to traditional recordings of Aum chanting to internalize the tonal quality and pacing. Sit quietly, take a full breath, and chant Aum aloud three times, allowing the sound to resonate through your body. Notice where the vibration settles—throat, chest, head. For study, read the Mandukya Upanishad (available in English translation by Eknath Easwaran or Swami Nikhilananda) to understand the metaphysical context. If local, seek out kirtan circles, satsang gatherings, or teachers trained in mantra yoga and advaita vedanta. Online platforms like the Sivananda Yoga Vedanta Centers offer guided Aum meditation sessions. Consistent daily practice, even five minutes, builds familiarity and depth.
