In the practice of Sannidhi Yoga Nidraa, rooted in the Rishiculture Gitananda tradition of Classical Yoga, the sadhaka lies in Shava Asana with the head directed towards the North and the feet towards the South. To many, this orientation may appear unusual because of the widespread cultural belief in India that one should never sleep with the head towards the north. Traditionally, this direction is associated with the positioning of a dead body. Yet within the yogic framework, this very symbolism becomes deeply meaningful.
Yoga Nidraa begins in Shava Asana, the ‘corpse posture.’ The Sanskrit term itself reveals the inner philosophy of the practice: Shava means corpse, and Asana means posture. In entering this posture, the practitioner consciously simulates the condition of death, not in a morbid sense, but as a transcendental process of disidentification from the body, senses, and egoic mind. One learns, momentarily, to experience what it means to ‘die’ to habitual identification. The body becomes still, silent, and surrendered while awareness remains alert and witnessing. Thus, Yoga Nidraa becomes not merely relaxation, but a rehearsal for transcendence.
Within the Gitananda tradition, the north–south alignment is also linked to the understanding of the human being as an electromagnetic organism existing within a greater cosmic field. Modern science recognizes that the body continuously generates measurable electromagnetic activity. The electrical impulses of the heart are recorded through the electrocardiogram (ECG), while the brain’s activity is measured through the electroencephalogram (EEG). Every heartbeat, neuronal firing, muscular contraction, and cellular exchange involves subtle bioelectrical processes.
The nervous system functions through electrochemical signalling, and the heart itself generates a powerful electromagnetic field extending beyond the physical body. In this sense, the yogic conception of prana as a dynamic life-force finds an interesting parallel in modern biophysics. We are not isolated mechanical entities but dynamic energetic systems interacting continuously with the environment around us.
The Earth too possesses its own geomagnetic field extending from the north pole to the south pole. Many species in nature, including migratory birds and marine animals, demonstrate sensitivity to this geomagnetic orientation. Ancient yogic traditions intuited that the human organism also responds subtly to these terrestrial energies. Aligning the body along the north–south axis during Yoga Nidraa may therefore facilitate a harmonious energetic resonance between the individual organism and the larger electromagnetic matrix of the Earth.
A logical question naturally arises: if similar poles repel each other in magnetism, why would orienting the head towards the north be beneficial? The answer lies not merely in physical magnetism, but in the deeper yogic understanding of the relationship between the microcosm and the macrocosm.
Yoga Darshana and Samkhya assert that the individual being (vyashti) is a reflection of the universal being (samashti). The apparent separateness experienced by the individual arises from avidya, fundamental ignorance. From this ignorance emerges asmita, the egoic identification that says, “I am separate.” We identify with body, mind, emotions, and memories, believing them to be our true identity. Yet Yoga declares that our essential nature is Purusha: pure consciousness, eternal, unchanging, and witnessing.
The world of thought, sensation, emotion, and material existence belongs to Prakriti, primordial nature. Human suffering begins when consciousness forgets its transcendental nature and becomes entangled in the modifications of Prakriti. This manifests as attachment and aversion, pleasure and pain, craving and fear.
Maharishi Patanjali explains this through the principle of “bhoga-apavargartham” — the union of Purusha and Prakriti exists for experience and eventual liberation. Through embodied existence, consciousness undergoes experiences that ultimately lead to discriminative wisdom and freedom from ignorance.
Sage Vasistha in the Yoga Vasistha further teaches that the cause of this union is desire itself, functioning through the dual movement of attraction and repulsion. In Yoga and the Bhagavad Gita these are termed raga and dvesa, attachment and aversion. Human life constantly oscillates between what it seeks and what it avoids.
Thus, the northward orientation in Sannidhi Yoga Nidraa becomes far more than a physical instruction. It symbolizes alignment with the cosmic order. The practitioner consciously enters Shava Asana, surrendering egoic identity, harmonizing the individual field with the Earth’s field, and contemplating the truth that the individual is not separate from the universe.
Ultimately, Yoga Nidraa is not merely a technique for relaxation. It is a sacred process of dissolving false identification. In the stillness of the corpse posture, the sadhaka encounters the essential teaching of Yoga: that beyond attraction and repulsion, beyond raga and dvesa, beyond birth and death, beyond Prakriti itself, shines the silent reality of Purusha — pure awareness, eternal and free: Sat Chit Anandam.
