The Science of Kriya Yoga (Autobiography of a Yogi, Ch. 26)
Kriya Yoga has often been called a spiritual science. This is not a metaphor. The practice operates on principles that can be observed, measured, and verified, working with the subtle anatomy of the human being in ways that…
The Subtle Body
Yogic science describes a subtle body composed of energy channels (nadis), energy centres (chakras), and the coiled spiritual energy at the base of the spine (kundalini). While these structures are not visible to the physical eye, their effects are unmistakable to the practitioner.
The Nadis
72,000 subtle energy channels carry prana throughout the body. The three principal nadis — Ida, Pingala, and Sushumna — form the primary pathways for spiritual energy.
The Chakras
Seven major energy centres align along the spine, each governing different aspects of consciousness, from basic survival to spiritual awakening.
Kundalini Shakti
The dormant spiritual power coiled at the base of the spine. Through Kriya practice, this energy is awakened and guided upward through the chakras.
The Kriya Technique
The core Kriya technique involves the conscious direction of life force (prana) along the spinal column. Through a specific method of breathing and inner awareness, the practitioner:
Concentrates Prana
Gathers the scattered life force from throughout the body.
Directs It Upward
Sends the energy up the Sushumna nadi (central channel).
Opens the Chakras
Each energy centre is awakened and purified in sequence.
Reaches the Crown
The energy unites with the divine consciousness at the Sahasrara.
Modern Scientific Research
Contemporary neuroscience and physiology have begun to validate many of the claims of yoga science. Studies have shown that practices like Kriya Yoga:
Increase Heart Rate Variability
A key indicator of autonomic nervous system health and stress resilience.
Strengthen the Prefrontal Cortex
The brain region responsible for executive function, decision-making, and emotional regulation.
Increase Grey Matter Density
Regular meditation has been shown to increase grey matter in areas associated with attention, emotional regulation, and self-awareness.
The Ultimate Experiment
Science can measure the physiological correlates of Kriya practice, but the deepest transformation — the direct knowledge of one's own divine nature — remains a subjective experience that each practitioner must verify for themselves. As the masters say, "The proof of the pudding is in the eating."
