In Haanel's framework, the physical organ system of the subconscious (subjective) mind, as distinguished from the cerebrospinal system of the conscious mind.

The sympathetic nervous system in New Thought philosophy, particularly Charles Haanel's framework, represents the physical organ system of the subconscious or subjective mind. This system operates through the solar plexus as its central organ and connects to the cerebrospinal system via the vagus nerve. Unlike medical definitions focusing on fight-or-flight responses, New Thought views this system as the physical mechanism through which subconscious mental activities manifest in the body and influence health.

Understanding Sympathetic Nervous System in New Thought

In Haanel's framework, the physical organ system of the subconscious (subjective) mind, as distinguished from the cerebrospinal system of the conscious mind. The Solar Plexus is its central organ. The vagus nerve connects the two systems.

Within New Thought, particularly as articulated by Charles F. Haanel, the Sympathetic Nervous System (SNS) is posited as the physiological interface of the subconscious mind, a crucial distinction from the cerebrospinal system's role in conscious thought. This framework highlights the SNS, with the solar plexus as its central hub, as the primary conduit for the manifestation of subconscious desires and beliefs into physical reality. Its significance lies in bridging the metaphysical principles of mind power with a tangible biological mechanism, offering a scientific-spiritual explanation for how thoughts and emotions influence the body and external circumstances. This conceptualization provides a practical pathway for individuals to consciously engage with their subconscious through the SNS, thereby influencing their health and life experiences.

What the Teachers Say

Charles Haanel
The Master Key System

Haanel identified the sympathetic nervous system as the physical counterpart to the subconscious mind, with the solar plexus serving as its central distribution point. He taught that this system operates independently of conscious will, governing vital functions and responding to mental states and emotions. According to Haanel, the sympathetic system connects directly to universal intelligence, making it the pathway through which thought becomes physical reality. He emphasized that understanding this system's relationship to consciousness allows individuals to consciously influence their physical conditions through proper mental direction.

Thomas Troward
Edinburgh Lectures on Mental Science

Troward described the sympathetic nervous system as the physical mechanism through which the subjective mind operates upon the body. He viewed this system as completely involuntary, responding automatically to mental impressions without conscious interference. Troward taught that the sympathetic system demonstrates the mind's power over matter, as it translates mental states directly into physical conditions. He emphasized that this system operates according to suggestion, making it the physical channel through which mental healing and transformation occur.

Sympathetic Nervous System vs. Cerebrospinal Nervous System

New Thought philosophy distinguishes between two primary nervous systems that correspond to different aspects of mind. While both systems are essential for human functioning, they operate through different principles and serve distinct roles in consciousness.

Etymology

The term "sympathetic" originates from the Greek "sympatheia," meaning "fellow feeling" or "affinity," from "syn" (together) and "pathos" (feeling, suffering). This reflects the system's interconnectedness and its role in coordinating bodily responses. "Nervous system" derives from the Latin "nervus," meaning "sinew" or "nerve." The combination describes a system of nerves that operates largely unconsciously, orchestrating the body's involuntary functions and emotional responses, thus exhibiting a "sympathy" with internal states.

How to Practice This

Practitioners of New Thought, following Haanel's insights, often focus on the solar plexus as a point of concentration for directing mental energy. Techniques may involve deep breathing exercises, visualization, and affirmations, all aimed at consciously influencing the subconscious mind via the SNS. For instance, one might visualize desired outcomes while focusing on the solar plexus area, believing this directs the subconscious to manifest those outcomes. Regular practice of these methods is thought to harmonize the conscious and subconscious minds, leading to improved well-being and the realization of goals through the physiological pathways of the SNS.

Connection to Manifestation

The sympathetic nervous system serves as the primary physical mechanism through which thoughts and mental states manifest as bodily conditions and life circumstances. In New Thought practice, practitioners learn to influence this system through meditation, visualization, and emotional alignment with desired outcomes. Since the sympathetic system responds automatically to mental impressions, maintaining positive mental states and clear intentions allows the subconscious mind to work through this physical network to create corresponding external results. Understanding this system's role helps explain how mental causation operates through physical channels to produce tangible manifestations in health, relationships, and material conditions.

Frequently Asked Questions

How does the sympathetic nervous system differ in New Thought from medical understanding?

While medical science views the sympathetic nervous system as controlling fight-or-flight responses, New Thought philosophy sees it as the physical organ of the subconscious mind. In this framework, it serves as the mechanism through which mental states directly influence physical conditions and life circumstances, operating as a bridge between consciousness and material reality.

What is the relationship between the solar plexus and the sympathetic nervous system?

In New Thought teaching, particularly Haanel's system, the solar plexus functions as the central organ of the sympathetic nervous system. It serves as the primary distribution center for subconscious mental activity, receiving and transmitting mental impressions throughout the body and connecting individual consciousness with universal intelligence.

How can someone consciously influence their sympathetic nervous system?

New Thought practitioners influence the sympathetic nervous system through mental practices like meditation, visualization, and maintaining positive emotional states. Since this system responds automatically to mental impressions and suggestions, consistent mental discipline and alignment with desired outcomes allows conscious direction of its normally involuntary functions.

Why is the vagus nerve important in New Thought philosophy?

The vagus nerve serves as the connecting link between the sympathetic nervous system (subconscious mind) and the cerebrospinal system (conscious mind). This connection allows communication between conscious intention and subconscious execution, enabling practitioners to consciously influence normally automatic bodily functions and mental processes.

How does the sympathetic nervous system relate to mental healing?

In New Thought philosophy, the sympathetic nervous system is the primary pathway through which mental healing occurs. Since this system translates mental states directly into physical conditions, healing practitioners work to impress positive, healthy thoughts upon it, allowing the subconscious mind to restore normal bodily functions and eliminate disease patterns.
