The Yoga Nidra Mantra is associated with the practice of yogic sleep, a state of conscious deep relaxation that lies between waking and sleeping. While the term 'Yoga Nidra' is most famously elaborated in the medieval text *Yoga Nidra* (a section of the *Devi Mahatmya*), the mantra itself draws from tantric and yogic traditions that emphasize the worship of the goddess Nidra as a form of the Divine Mother. In the *Devi Mahatmya* (Chapter 5, verses 8-13), the goddess is described as 'Nidra' (sleep) who grants both rest and liberation. The beej-akshara (seed syllable) 'Hreem' is often central to Yoga Nidra mantras, as it is associated with the goddess Bhuvaneshwari, who governs the dream state and cosmic illusion.
Phonetically, 'Hreem' combines the elements of fire (Ha), the sun (Ra), and the creative power (Eem), inducing a state of inner stillness. Another common mantra is 'Om Nidra Devyai Namah', which directly invokes the goddess of sleep. Traditional purposes include relief from stress, anxiety, and insomnia, as well as the integration of spiritual practices through deep subconscious reprogramming. The *Mantra Mahodadhi* (Chapter 7) recommends chanting such mantras 108 times before sleep or during a guided Yoga Nidra session, ideally in a dark, quiet room.
The *Shaktisangama Tantra* (section on Nidra) states that regular practice can lead to siddhis (psychic powers) and profound peace. Cautions include avoiding practice while driving or operating machinery, as the deep relaxation may induce actual sleep. It is also advised to not practice immediately after a heavy meal. The mantra is chanted in a soft, soothing tone, often accompanied by breath awareness.
For professionals, this practice is recommended to restore work-life balance and enhance cognitive function through deep rest.
Salutations to the goddess Nidra (sleep).
The seed syllable 'Hrīṃ' (ह्रीं) is often central, combining 'Ha' (fire), 'Ra' (sun), and 'Īṃ' (creative power), inducing inner stillness.
