The Advaita Vedanta Dhyana Mantra is a meditative invocation rooted in the non-dual philosophy of Advaita Vedanta, as systematized by Adi Shankaracharya (c. 8th century CE). Its textual origin lies in the principal Upanishads, particularly the Chandogya Upanishad (6.8.7) which declares 'Tat Tvam Asi' (That Thou Art), and the Brihadaranyaka Upanishad (1.4.10) which states 'Aham Brahmasmi' (I am Brahman). These mahavakyas (great sayings) form the core of the mantra's contemplative focus. The mantra is associated with the supreme reality, Brahman, understood as pure consciousness, and the individual self (Atman) which is identical to Brahman.
The beej-akshara (seed syllable) 'Om' is often prefixed, representing the primordial sound and the ultimate reality. Phonetically, 'Om' encompasses the three states of waking, dream, and deep sleep, transcending them into the fourth (turiya). The traditional purpose of this dhyana mantra is to realize the non-dual truth that Brahman alone is real, the world (jagat) is illusory (mithya), and the individual self is none other than Brahman. This is encapsulated in the famous verse 'Brahma Satyam Jagan Mithya Jivo Brahmaiva Na Parah' (Brahman is true, the world is false, the individual self is Brahman and nothing else), attributed to Shankara's Vivekachudamani (verse 20). Chanting this mantra is believed to purify the mind, remove ignorance (avidya), and lead to liberation (moksha) through direct knowledge (jnana).
Recommended chanting context includes early morning (brahma muhurta) in a quiet, clean space, seated in a meditative posture. The count is traditionally 108 repetitions using a rudraksha mala, focusing on the meaning of the words. No specific ritual setting is required, but a sattvic diet and ethical conduct are advised. Cautions: This mantra is intended for those with a strong foundation in Vedantic study and a qualified guru, as the non-dual teaching can be misinterpreted without proper guidance. It is not recommended for those seeking material benefits, as its sole aim is spiritual realization.
Brahman is true, the world is false, the individual self is Brahman and nothing else.
The mantra begins with the seed syllable 'Oṁ', which is the primordial sound representing the ultimate reality. 'Oṁ' encompasses the three states of consciousness (waking, dream, deep sleep) and transcends them into turīya, the fourth state. It is the beej-akshara for Brahman.
